Classic Features, All-Purpose Cutter

The BN-L heavy-duty all-purpose cutter begins with a contoured handle that fits securely in your hand. The stainless steel blade channel extends the length of the cutter to support the blade and heavy-duty cutting. The ratchet-wheel lock allows the blade to be extended into any position for added flexibility when cutting thick materials or in tight spots. This cutter also has an easy, tool-free blade change for added convenience. Perfect for both right- and left-handed use.
