This slotted razor blade knife has a relieved blade holder that exposes a longer cutting surface of the blade to more efficiently slice through thick carpet pad. The handle is angled upward to prevent dragging of the knuckles on the pad, and is knurled on both sides for improved grip. The body pivots open for blade storage by loosening the folding thumbscrew. Blades: No. 308. No blades are included with this knife. Net weight: 4 oz.
