Locking safety knife
November 24, 2019
The American-made Lewis K710 Locking Safety Knife features a spring-loaded, locking safety hood over the blade. Once contact is lost with the cutting surface, the safety hood snaps shut and locks over the blade, preventing injuries common to follow-through motion. The Lewis K710 also features two depth settings and easy blade changing with no tools required.
