Meet the Trim-Lock, a revolutionary cutting and trimming tool sure to make your life easier. The Trim-Lock is meant to be used to cut half square triangles, as well as for use in fussy cutting. The magic happens when you apply pressure to the handle, which engages the grippy material on the base of the Trim-Lock on your fabric, keeping your fabric in place so you can cut, and spin, your fabric without having to readjust your template for every cut.

This particular Trim-Lock is a 4" square and made with 1/4" thick acrylic.
