Best Sprue Cutter Reviews
Creating plastic models, miniature and figurines is a great hobby in many ways. Besides letting you spend time in the most engaging and creative way possible, it helps you in improving your concentration and discipline. Also, you eventually end up with a valuable piece of art.
However, the fulfillment of creating models and miniatures largely depends on the level of finishing you achieve with your project. The connecting pieces (sprue) of a model often develop some unwanted buildup during the process of injection molding. They don’t serve any purpose and only spoil the appearance of the given miniature or model. You can get rid of those unwanted pieces with cutting pliers without damaging intricate and tiny pieces of the sculpt.

Since finishing a model while getting rid of its sprue parts requires precision, it is best to not use any old off-the-shelf pliers for this job. We have searched for the best “sprue cutters” among the host of regular cutters and nippers available in the market. The great news is that most of our favorites won’t break the bank!
1. Hakko Micro Cutter– Best Overall
We are starting our list with a cutter that is arguably the best sprue cutter out there. Even though Hakko markets it as a flush cutter for copper wires, its function for getting rid of sprue parts is equally impressive. The primary feature that makes it ideal for sprue cutting is its “micro” size. It has an 8mm long jaw with a pointed nose, enabling it to reach tricky spots on a plastic or metal mold.
The cutter is made of heated-treated carbon steel that puts a seal of approval on its long operating life and durability. The steel is also parkerized for the prevention of glare and improved corrosion resistance. Unlike other cutters, this one won’t rust even after several years of use. And check out the great price point!
- Curved for-edge and nonslip handgrip— improved comfort and control
- Spring return to reduce fatigue
- Also available in packs of 2 and 3

These jaw-cum-blades are made of top-quality Chrome-Vanadium steel alloy. This metallic alloy makes it certain that the blades don’t lose their sharpness with use.

3. Klein Tools D275-5 Lightweight Flush Cutter– Best for Repetitive Cutting
This Klein Tools’ flush cutter is equally good for taking care of the unwanted small parts on any plastic mold. The reason we consider it suitable for sprue cutting is its ultra-slim profile that lets you access confined spaces on a molded model without breaking a sweat.

7. Valtcan Prime Sprue Cutter for Model Kits– Best for Thick Plastic Sprue Cutting
If you make large models that use thick plastic pieces, then consider using these cutting pliers by Valtcan. This sprue cutter has a long handle that increases its moment arm to let you make cuts with lesser use of force. The spring installed between the two handles also reduces the time you spend on finishing your models.
The other distinctive bit about this sprue cutter is the extension control pin fixed on one side of the jaws. It restricts the extension of pliers to a certain limit, which helps when you work in confined spots of the model.

Things to Consider While Buying Sprue Cutters
Take these factors into account while buying sprue cutters.
The blades/jaws of a sprue cutter must be thin, sharp, and low profile so they can easily reach all small and delicate sprue parts and gates with ease. Also, make sure that they are made of top-quality steel and alloys. You can choose from stainless steel, carbon steel, and chrome-vanadium steel alloy in cutter blades. Please note that the most expensive is also the most fragile blade.
Handle and Grip
A sprue cutter must have a long handle that doesn’t just easily accommodate your hand but also increases the moment arm. Moreover, they should be draped in soft plastic or rubber grip. These characteristics collectively make the use of sprue cutters fatigue-free.
Make sure that the sprue cutter you buy must be spring-loaded. When a cutter features a spring in between its jaws, it makes its retraction and extension easy. A spring-loaded cutter makes long sessions of model and miniature finishing less hectic.
We hope that the above reviews and buying guide help you in picking the best sprue cutter for your model and miniature finishing. If we are to make any suggestions, we would like to suggest our readers Hakko Micro Cutter. It features sharp and narrow blades that make clean cuts. Hakko Micro Cutter also sports a spring return mechanism. On top of that, it lies at a reasonable price point.
What is de-gating?
It is the process of removing the gate from a model or miniature molded from plastic. In plastic injection molding, the gate represents the opening through which molten polymer is injected into the final part of the mold.
Is there an alternative for sprue cutters?
You can use tweezers in place of sprue cutters but only for unwanted plastic parts that are in front and not firmly connected to the rest of the mold. Tweezers are not suitable for large plastic sprue parts and hard-to-reach spaces, nor will they give clean break-off.
When to change a sprue cutter?
When you observe that your sprue cutter is not making clean cuts or has started causing tearing and pinching, you may need to buy a brand-new cutter.
