The SPN-120 Ultimate Nipper is widely regarded as the gold standard, designed for unparalleled precision and clean cuts. Engineered in Japan with expert craftsmanship, these professional-grade side cutters feature an ultra-thin single-blade design that delivers a ultra-smooth finish with minimal stress on the plastic.
Ideal for serious modelers, the SPN-120 makes removing parts from runners effortless, reducing sanding and cleanup while preserving fine details. Its ergonomic grip and razor-sharp cutting edge ensure comfort and control even during long building sessions.
Usage Precautions
- Designed only for plastic model runners – do not use on metal, polycarbonate, or resin, as this may damage the blade.
- Rated for material width of <3mm (PS, PP, ABS) or <1mm (clear/translucent plastic).
- Avoid twisting or cutting thick gates in one motion; instead, cut in two stages for best results.
- The cutting edge is extremely sharp and delicate — store with the blade guard attached when not in use.
- Keep out of reach of children and handle with care to prevent injury.

Question
Is it possible to sharpen the blade on these or do you just have to buy another one?
Answer
Sharpening nippers may improve near term effectiveness at the cost of shortening the tool's lifespan. There are youtube tutorials on how to do it.

Question
Can these nippers cut hard clear plastic (Such as the clear plastic on the destroy mode Unicorn Gundam) and rubbery plastic (Like beam sabers)?
Answer
Yes to both. As long as the gates are under 3mm across and you don’t use the blade tip to cut harder plastics, you shouldn’t have any issues. Always make perpendicular cuts as side cuts puts undue stress on the blade and may cause it to snap.
