The grip spear is a small-sized knife with a tapered blade that makes it ideal for spearfishing. The blade is made in stainless steel. It features a high precision dagger point tip. One side is an extra rigid serrated blade for sawing, the other side is a skillfully crafted straight blade. It features an ergonomic non-slip handle grip and a hole to add a lanyard (not included). The knife comes with a sheath that can be attached to the bcd shoulder strap. The sheath has a locking mechanism that prevents the knife from falling out. With 2 rubber straps (included) you can fix the sheath to your leg or your arm. The straps are 20 in (50. 8 cm) long. Great for spear fishing or scuba diving; as primary knife or back-up
