OFLA OL-ML High-Durability Knife.

This knife features an all-metal body and an AUTO LOCK mechanism.
The all-metal body allows you to easily cut through a variety of materials, including plywood and thick rubber.
The blade locks securely, making it very convenient to use.
Metal guides securely hold the blade and prevent play.
After use, the blade can be simply retracted, completely concealed within the body.
This protects the knife from cuts and dulling.
As the blade becomes dull, the dull segment can be broken off with pliers or easily replaced with a new one.

The knife's metal trapezoidal handle ensures a secure grip.
Ideal for cutting durable materials such as cardboard, leather, rubber, and similar materials. The Olfa OL-ML knife uses an 18-millimeter blade.
A plastic cap on the back helps secure the blade when finished. An automatic mechanism ensures a secure blade lock.
