Overview
The GMMS-17 pairs a rolling blade with a 17 inch handle, a build more common to flooring and carpet cutting tools than to a standard fixed knife. At 2.31 pounds it has enough heft to push a rolling blade through resistant material without much hand fatigue.
A rolling blade rides on a wheel rather than a fixed edge, which lets it track a straight line through carpet, underlayment, rubber matting or similar sheet material with less drag than a straight blade. The 17 inch handle gives reach and leverage for long cuts made from a standing position.

Who it's for
Fits flooring, carpet or general contracting work that involves long, straight cuts through sheet material. Not built as a general-purpose or pocket knife.
Strengths and trade-offs
Drawn from this product's published specifications.
- Long 17 inch handle for reach
- Rolling blade tracks straight cuts
- Not suited to detail or general cutting work
Performance notes
The rolling wheel design keeps the blade tracking a straight line under its own weight, which matters most on long cuts where a fixed blade tends to wander. The 17 inch handle keeps the user upright rather than bent over the material.
