Take the guess work out of trimming your touring skins. This universal trimming tool from Pomoca will ensure a precise cut every time. It also has an off set to compensate for the edge as well as dual blades to go forward or switch. The oversized handle provides a sturdy and sure grip, so slippage is never an issue.
If you take your time to lay the skins flat and keep your ski steady, cutting is very easy. Cut from tip to tail and go slow. Works great.
