7 Essential Features of Sprue Cutters and Precision Nippers

Here’s a quick overview of what I see as important factors to consider in any cutting implement. Back when I was younger, I used to whittle and carve wood. I learned a lot from this hobby.

Redgrass Games Sprue Cutter and Precision Nipper Review - RGG sprue cutter RGG precision nipper - a radial array of cutting tools for working with plastic and resin.
A variety of plastic/resin cutting tools, and a traditional wire cutter (which I relied on for many years for pewter metal modeling).

For example, a durable knife that keeps its edge even through hard use is worth its weight in gold. Of course, there are many other factors that go into what makes an effective and fun cutting tool. Sprue cutters and nippers are no different.

Here are 7 things you should know about finding the right model plastic sprue cutter/nipper for your hobby work.

  1. Shape of cutting blade edges
  2. Ergonomics and comfort
  3. Size and weight
  4. Sharpness
  5. Durability
  6. Ease of maintenance
  7. Price

1. Shape of Cutting Blade Edges

When choosing a sprue cutter or precision nipper, the shape of the cutting blade edges is important. Fine-pointed, steep beveled blades (i.e., with asymmetric cutting edges in a compact tip), like those you find in the Precision Nippers, are excellent for intricate cuts in hard-to-reach spaces. Longer, flat blades, such as in the Sprue Cutters, are ideal for straight and accurate cuts on larger sprues or when you want to work more quickly.

2. Ergonomics and Comfort

Ergonomics play a vital role in tool selection. Handling comfort is a top priority for any pleasant hobby experience. Look for tools with a comfortable handle designed to fit comfortably in your hand, reduce strain, and improve control.

The RGG Sprue Cutter and Precision Nipper have curved handles that naturally fit the relaxed position of your fingers and palm in a rested posture. You want tools that can help reduce hand cramping as they are designed to work within your natural range of motion. The rubberized or non-slip grips give you more control over the course of your work. The orange color also gives you a visual cue of where your hands should go.

3. Size and Weight

This is related to the ergonomics of a tool. Compact and lightweight tools are preferable as they are easy to maneuver, reducing hand fatigue, and allow for precise control. In some cases, extra weight or mass does help with stability or torque applications, such as you may want in seam scrappers or wrenches.

If you’re traveling with your hobby, you’ll want tools that store away easily.

But with cutting tools, a light weight system that fits your natural grip make these types of tools easier to use, and improves comfort and performance. The RGG cutters and nippers are a perfect size for these reasons and they also happen to travel well. Just remember to use the blade tip covers when you’re storing them in your travel bag or case.

4. Sharpness

A blunt tool is useless. The sharpness of a tool’s blades directly impacts the quality of the cut. Finely sharpened blades, like those on the Redgrass Games tools, provide clean, precise cuts with minimal effort. If your cutters have dull edges, then you’ll have to apply more force to finish the cut. This can increase the risk for damaging the delicate model part, or make the edge prone to slippage leading to a misaligned cut or injury to yourself.

The blade on the RGG sprue cutter is really-sharp! Will it stay that way? In my testing, it has held up very well with weeks of use.

The RGG sprue cutter and nipper are super sharp. In fact, they are currently the sharpest bladed tools I own aside from my hobby knives.

5. Durability

Durability is a key consideration. Look for tools made from robust materials, like hardened steel for blades and high-quality plastic or metal for handles, to ensure they withstand extended use. The Sprue Cutter and Precision Nipper are great examples of such durable tools. Their handles are entirely metal and extend right into the cutting tips.

6. Ease of Maintenance

The ideal tool is easy to maintain. Look for designs that allow for easy cleaning and infrequent sharpening, much like the Sprue Cutter and Precision Nipper. A simple wipe down after use can prolong the life and performance of your tools. Using knife oil on bladed tools also keeps rust or patina from forming, improving performance and service life. I use knife pivot lube on my wood whittling tools (used in this project) to keep them in top condition.

7. Price

While cost is an important factor, it’s crucial to consider the value you’re getting. The Sprue Cutter and Precision Nipper’s combination of robust design, durability, and precision cutting capabilities offers a compelling value for their price.

While I was not initially expecting there to be a noticeable difference with RGG’s tools as compared with less expensive cutters I’d used before, I quickly realized what I was missing. Read more below for why. I have to take my advice: As with anything you buy for the hobby, balancing cost with quality will lead to a worthwhile investment in your model-making toolkit.


Sprue Cutter Versus Precision Nippers: What’s the Difference?

What’s the difference between a sprue cutter and precision nipper? I had to dig deeper to find out more about their similarities and differences. Picking between the two? It all boils down to what you need and how you’re gonna use them. Basically, your choice depends on what jobs you’ve got lined up for these tools.

Redgrass Games Sprue Cutter and Precision Nipper Review - RGG sprue cutter RGG precision nipper - side by side shot of the two tools on a black backdrop
Sprue cutter (left) and Precision nipper (right)

Sprue Cutters

These tools are designed to remove parts from sprues (the frames to which parts of plastic or resin model kits are attached). Sprue cutters typically have a broader, flat blade which is designed to cut closer to the part without damaging it. They’re usually strong and robust, capable of handling larger, thicker sprues. The RGG sprue cutter has is fantastic for breaking down general stock plastic/resin model kits without worrying about damage to the tool (within reason).

Precision Nippers

These are fine-tuned for more intricate and delicate work. Precision nippers usually have a narrower, sharp-edged blade for precise, close cuts. This allows model makers to remove smaller parts or trim away excess plastic with higher precision, including in hard-to-reach areas.

A closer look at the RGG nippers will reveal an asymmetric blades. One side is beveled with a steeper angle than the other. While the other continues to have an extremely sharp single edge. In this case, this single side cutter configuration places less stress on more fragile material, e.g., fine cast resin, allowing for a clean cut with less risk of breakage or cracking of the parts.

Which should I choose?

If I had to choose just one tool, the sprue cutter or precision nipper, I’d buy the sprue cutter. The sprue cutter may not create the flush, super-smooth cuts through small plastic or resin pieces that the precision nippers can make. But the sprue cutter is more durable and versatile.

The sprue cutter also appears to leverage more force easily. And, while this could risk some cracking or breakage on very delicate materials on very small parts, the sprue cutters can do quite a lot of work in any modeling task with some gentle care and patience.

In general, imho, you’ll find more uses with the sprue cutter in various hobby tasks. If you need the smoother, flush-cut surfaces that a precision nipper provides and you only have a sprue cutter, you can always clean up the material surface with sandpaper, a small file, or a hobby knife.

Arrival and Unboxing of the RGG Sprue Cutter/Nipper

My experience with Redgrass Games has always been excellent. So, I was not surprised that the tools arrived safe and sound. Both the sprue cutter and precision nipper arrived packaged in simple, yet effective blister packs with minimal plastic packaging.

On the back of each package, I found instructions for best uses for the cutter/nipper. I also noted a warning to avoid cutting material with only the tips of the blades, as this could snap those tips.

Cautionary instructions on the RGG precision nipper
Notice the instructions for the RGG precision nipper? One edge of the cutting tool is ultra sharp. It provides one of the most distinctive cutting and trimming experiences in my testing. And, the nipper doesn’t require much force to slice through plastic, creating thin translucent slivers during trim and smoothing work.

Removing these tools from the packaging was a simple process. Once I removed the protective wrapping, the cutter and nipper greeted me with bright orange textured handles, fine honed edged blades, and a nice springy handle response–dampened perfectly. See below about these tools’ handling and ergonomics.

The dampening spring in the RGG precision nipper is perfectly tensioned for maximum control and comfort. I thoroughly enjoyed using this for finer scale plastic work.

The cutting ends of each tool came with translucent rubber caps to protect the metallic tips (and you) from damage. I put these plastic caps aside, as I know I’d want to use them later if I ended up traveling with the cutters. I often take my hobby with me on trips to conventions or for business meetings away from home.

First USE and Lasting Impressions: Cuts like a Hot Knife Through Butter

I performed various tests on random plastic and resin sprues and bits I had. I also assembled a complete box of Tau XV25 Stealth Battlesuits using these cutters/nippers. It’s a new Warhammer 40k army and so why not start with fresh tools and in-depth look at how the Redgrass Games Sprue Cutter/Precision Nipper can help me.

Note that in the cutter and nipper a set screw prevents the two blade sides from touching too closely. The metal in each edge can damage the cutting tips if these screws aren’t calibrated properly. The good news is that my copies arrived with these set screws perfectly aligned, and I didn’t have to do anything to start working with the tools.

Without getting into the weeds, I would have bought them earlier if I actually knew how well they’d perform right out of the box. The RGG Sprue Cutter cuts through plastic modeling sprues like a hot knife through butter. Cliche, I know. But I’m lazy, and you all know what butter does when you slide a knife across it on hot toast.

Interesting Observations with RGG Sprue Cutters

Here’s a note about versatility. The Redgrass Sprue Cutters are touted as capable of handling both small-scale and large-scale model parts. I found this to be accurate. I’ve used them on a variety of sprues, from the intricate and tiny pieces of the Tau weapon bits to the bigger and more robust chunks of an landraider kit. I also worked on some resin blocks from a Forgeworld model I still had to work on.

For 3D printed miniatures, cleaning up build lines and removing scaffolding material is required for best results.

At some point, if you’re working with a variety of model types, sizes, and scales, e.g., Gunpla, tabletop miniatures, military scale models, the sprue cutter and nippers complement each other. With them together, you have the entire arsenal you need to handle any modeling assembly task.


How About Resin Models?

A quick word for working with resin. Because resin is a softer material than plastic, it could be a tad more fragile. Resin is prone to cracking, and does take a bit more skill to cut smoothly (despite its soft character).

While I won’t bore you with the same experiences I had with plastic (as resin snips and cuts easier), the character of an effortless cut through resin model pieces with either RGG tool was super easy. As with plastic, I felt that the low profile of the precision nipper in particular helped to reduce hand fatigue when working on detailed, intricate parts.


Best Way to Remove Miniature Plastic Components (Tips and Insight)

If you are a hobbyist who enjoys building models or miniatures, you know how important it is to remove the plastic components from the sprues without damaging them. Sprues are the plastic frames that hold the parts together and are usually attached to the parts by thin connectors. Sometimes, these connectors can leave unsightly marks or nubs on the parts when they are cut off, which can ruin the appearance of your model.

READ MORE: 30 MODEL KIT ASSEMBLY TIPS FOR PROS AND BEGINNERS

A oft recommended way to remove miniature plastic components from model kit sprues is to use both sprue cutters and precision nippers in a two-step process.

First, use the sprue cutters to cut off the connectors close to the sprue, leaving a small nub on the part. Then, use the precision nippers to remove the nub from the part, cutting flush with the surface. This way, you can avoid damaging or deforming the part and achieve a clean and professional look.

Here are some tips I found from various sources that should help you get the best results when removing the parts from sprues for miniatures or scale models:

  • Use flush side cutters to separate the parts from the sprues. RGG cutters/nippers have a flat or flush side, which you should place against the model part when cutting off the sprue.
  • Trim excess plastic leftover from the molds using precision nippers (easier, safer) or a hobby knife (requires a bit more skill and care).
  • Use a small file or sandpaper to smooth out any residual imperfections from the cut
  • A gap filler substrate can help you recreate the original surface if you accidentally damaged the part during the cutting process.

Comparison with Other Clippers, Cutters, and Nippers

Other nippers may look sharper or pretty in prime condition. But, in my comparison against Army Painter Cutters, also known as plastic frame cutters, or the single blade nippers that I found a long time ago in a hardware store, the RGG Sprue Cutters and Precision Nippers performed equal to or better than all of them.

The RGG sprue cutter and precision nipper should be used in a two step process for best results
Use these tools in a two-step process: 1) Apply the Sprue Cutter (left) to cut and remove parts cleanly and quickly from the plastic sprue, and then 2) trim parts with the Precision Nipper (right) to recreate the flush surface

The cost of affordable?

Upon closer inspection with “affordable” cutters, you can see that the quality of the steel, the grind at the blade edge isn’t as polished as the RGG offerings.

In my view, the GodHand Ultimate Nipper with its ultra-thin single-edged structure is probably the closest competitor to the RGG Precision Nipper. The Godhand nipper can sever plastic parts without stress compression marks, e.g., that white colorization, and leaves behind a smooth surface. Of course, the Godhand Ultimate Nipper is also more expensive than the RGG Precision Nipper.

The high quality steel for the RGG sprue cutters in particular impressed me, holding an extremely sharp single edge even when I tried the tools on metal (pewter) model parts.

Quality wire snippers. They work, but are heavy and require a bit of force to split plastic because they aren’t very sharp. Not ideal for long assembly sessions, and could get uncomfortable.

By the way, while I don’t recommend you cut materials other than plastic or resin, I’m fairly sure a few snips in soft metal or wood wouldn’t hurt these tools. Just be aware these materials are outside their intended function.

A Comparison: The Army Painter Frame Cutter?

The Army Painter Plastic Frame cutter features sturdy red rubber grips and spring-loaded cutting blades that function well as intended. They require a bit more force to split plastic parts than the RGG sprue cutter, and leave behind a rough surface.

In a direct comparison with The Army Painter Plastic Frame Cutter, the RGG sprue cutter does easily perform in a class of its own. Here, the RGG Cutter stands out with its ultra-sharp steel blades and a slightly higher precision due to a slimmer, pointed tip.

Budget cutters work well, but often leave a nub of plastic that requires clean up.

However, the Army Painter Cutter, being less expensive, provides the function for those looking to simply remove plastic parts for their kit assembly workflow, i.e., albeit with a rougher cut that will require clean up for best results.

For large, thick cuts, use a less expensive budget cutting tool. You’ll protect your finer instruments from excess wear and tear, when precision and accuracy are paramount.

The Army Painter rubber-coated handle works fine for extended crafting sessions but I realized quickly why the RGG sprue cutters/nippers cost more. The RGG offerings are lighter weight, easier to handle and maneuver in tight places, and I felt more confident working quickly.

There are certainly other premium tool cutters in my tool box that can cut-down polystyrene modeling plastic and resin. But they were designed primarily as industrial tools, e.g., wire cutters, and have a heft and handling to them that aren’t optimized for accurate, flush and smooth cuts that a hobbyist would prefer.

Blade Maintenance

You should not need to sharpen your sprue cutter or nippers for a very, very long time (if ever), as long as you handle them with care, avoid cutting anything other than plastic or resin (e.g., soft materials).

To ensure long service life of the blades in these tools, make sure you avoid cutting any material that could dull them. Also, make sure to replace the plastic cap that came with each tool to protect the tips from damage.

Knife oil is a specialized lubricant you use to maintain, protect, and improve the functionality of bladed tools. Every few months, I apply a small amount to the pivot point and blade-edge on my cutting tools.

While I can’t tell you exactly what kind of metal the RGG blades are made of, they are certainly strong and seem quite durable. If I had to guess, based on their performance and the common materials used in such tools, I would hazard they are possibly made of one of the standard steels used in blades for wire cutting tools, such as carbon steel, stainless steel, chrome vanadium steel, or even tungsten carbide.

If they are made with any of those steels I mention above, I know that knife oil can maintain a sharp-edged tool’s performance. A light dab of tool or knife oil on the blades and the pivot will keep any sprue cutter or nipper going for a very long time.


Conclusion

The Redgrassgames’ Sprue Cutter and Precision Nipper are amazing tools that surpassed my initial expectations. Their premium cost is justified by their performance in my use assembling miniatures and models for my growing Warhammer 40k army.

Despite my usual reluctance to spend more on hobby tools, these products have changed my mind when it comes to what ails me about assembly–the frustration with poorly snipped bits and parts that takes too long and produces an uneven cut that I spend tedious hours cleaning up with sandpaper or files. Precise cuts with the sharp RGG cutter or nipper did make this process much more efficient for me!

I suppose as with choosing between cheap or quality hobby paints, there are times when choosing the right (best) supplies will save you the hassle and frustration of unexpected results.

Compared with a similarly priced competitor cutting tools, Redgrass Games’ offerings held up well. Regardless of one’s level of experience with model-making, the Sprue Cutter and Precision Nipper can be considered worthwhile additions to any hobbyist’s toolbox.
