The Cressi Borg Dive Knife is a modern, large knife with a futuristic design and a strong, tempered blade made of 304 Japanese stainless steel. 1 side of the stainless steel blade is straight-edged, while the other side is serrated right along the blade; they're both very sharp and effective for line cutting. The handle has an ergonomic design to ensure a secure grip even while wearing gloves. It's separated from the blade by a small techno-polymer thumb tab. The knife comes with a sheath that features a locking mechanism to allow 1-hand release. The sheath comes with 2 standard-issue straps to secure the knife to your leg.
