Power Advance Cold Knife

The revolutionary design of the Power Advance Cold Knife is a stroke of genius for the Auto Glass Technician. The Y-handle means extra power, extra strength and extra reach! The unique design of the adjustable Y-shaped attachment controls twisting and pitch, reduces arm strain and fatigue, and allows for raising or lowering for extra clearance. The rigid knife handle gives the technician greater control for pushing or pulling. Designed with a unique blade retaining method that lets you change the blade in seconds and set the blade to any depth, so the body of the knife will clear bonded mouldings.


Comes with one 1" blade. Made in the USA.
