Crain Quarter Moon knife used for trimming excess vinyl weld thread. Trims flush to the floor’s surface with a razor sharp curved blade.

Used for trimming excess vinyl weld thread flush to the floor’s surface, after the weld as cooled. The knife’s flexable top edge is razor sharp. Pushed against the weld excess this curved edge shaves the weld flush to the floor’s surface. This may be done in steps, first using the trim guide, and then making a final pass over the seam with the knife only.
