With four blade lock positions, this industrial knife cuts anything from cardboard to thick foam and fiberglass insulation. Its installed rounded-tip blade reaches a maximum cutting depth of 76 millimeters (approx. 3 inches). As with all Slice® tools, the Manual Industrial Knife has an easy, no-tool blade change that also lets you switch the blade orientation for left-handed users. And the blade is finger friendly®: it cuts effectively and is safe to the touch. The industrial knife’s ergonomic handle is made from durable reinforced nylon, designed to last through the toughest jobs. Convenience features include a built-in lanyard hole and a quick-release blade change button. The Slice zirconium oxide safety blade is non-reactive, never rusts, and lasts up to 11 times longer than metal blades.
