Generic 22-7 retractable utility knife trimmer 3pcs 20 blades

Three knives with twenty spare blades

This set supplies three retractable utility knives and twenty replacement blades in a single pack. The stainless-steel blades and plastic-metal frames are built for daily opening of boxes, cartons, tape and strapping in offices, workshops or home craft areas. Each knife fits one hand and retracts automatically when released.

Spring-loaded retraction and tool-free blade swap

Press the slider to extend the blade; let go and it springs back into the metal frame for safe carry in a pocket or tool belt. Changing a dull edge takes seconds: pull out the bottom cartridge, open the red latch, rotate or replace the blade, then snap the holder shut. No extra tools or screws are required.

Four cutting edges per blade for extended use

Every blade offers four usable corners, so the twenty included pieces yield up to eighty fresh edges before a restock is needed. The compact 3.86 by 0.91 frame handles cardboard, cord and packaging film comfortably, while the 1.54 by 0.71 blade length limits deep cuts in thicker sheet goods or dense foam.
