Mr. Hobby MT-107 Ultra Single Blade Nipper

The Mr. Hobby Mr. Ultra Single Blade Nipper (MT-107) is a precision cutting tool built around a single-edged blade design, manufactured in collaboration with Suzuki Blade Manufacturing. The ultra-thin stainless steel blade presses against a flat anvil side rather than meeting an opposing edge, which is what makes the difference when it comes to clean gate removal -- less stress transferred to the plastic means fewer stress marks left behind on your parts.

The handles are fitted with a stainless steel wire spring that opens them automatically after each cut, keeping your workflow steady. It can be released or removed if you prefer fingertip control. There's also a built-in breakage stopper that prevents the blade from over-closing under pressure, which is a genuinely useful safeguard on a tool at this price point. For best results, use the two-cut method: leave a small buffer of gate on the part with the first cut, then shave it flush with the thin edge on the second pass. The blade is designed for standard polystyrene and ABS plastic -- avoid thick runner sections, clear parts, and metal or POM joints to keep the edge in good condition.
