Olfa "HH-12B" 25 mm Hook Replacement Blades - 3 Pack

 When you need to protect your cutting surface or the material that lies beneath the cut, OLFA 25mm HH-12B Hook Snap Blades guard against accidental damage. The blade’s hooked shape uses a pulling action for cutting, rather than relying on a downward force that might damage the substance underneath. Each of these 25mm blades is comprised of four (4) segments that can be snapped off to expose a new sharp edge without the need for extra tools. Manufactured from premium carbon tool steel for an extra heavy-duty blade that maintains stability and sharpness, allowing you to cut with confidence. Cut easily through carpet, house wrap, nylon, shingles, & more. Fits with most 25mm snap knives.  Made in Germany.
