Fixed-blade utility knives and cutters minimize blade wiggle to make precise cuts. They have no retraction mechanism that could cause the blade to unexpectedly retract. Utility knives and cutters make pull cuts using small blades attached to a handle or ring. They score drywall and insulation and cut cardboard, plastic sheeting, card stock, cord, and more.
Fixed-Blade Utility Knives
The fixed blade of these utility knives provides a rigid edge to cut tougher materials than retractable-blade knives. The blade remains exposed and does not retract into the handle. Only one corner of the blade is exposed at a time, so the blade can be flipped to the fresh cutting edge when the first one dulls.
