The Slice Manual Industrial Knife extends 3 inches (76 millimeters) for cutting thick materials like foam, extremely thick corrugate, batting and insulation. This durable, five-position handle offers four cutting depths for a variety of jobs around the production floor or workshop. Blade stops offer the following cutting depths: 6 mm, 28 mm, 53 mm and 76 mm. The tool features a Slice finger-friendly blade that cuts effectively but is much safer to touch than standard metal or ceramic blades. Our no-tool blade change system also allows you to switch the blade orientation for left-handed users. Slice safety blades are chemically inert, non-sparking, oil free and never rust. They last up to 11 times longer than comparable steel blades.
