Born from water, the 112SBK H2O was originally developed for an elite military program. The N680 blade is chromium-molybdenum conventionally produced stainless steel with the addition of vanadium and nitrogen. Excellent corrosion resistance properties, especially in saltwater. Good hardenability and high obtainable hardness. High wear resistance and ability to preserve keenness. The lack of a point prevents the rescuer or diver from inadvertently injuring a victim who is being cut free from something restrictive. The serrated edge is great for sawing through rope or hose should the need arise, while also having a straight edge for your slicing needs. The rescue hook is perfect for cutting cords. The rubber overmold handle is textured to ensure you have a firm grip when it matters most. The 112SBK H2O is the perfect knife for your next diving adventure!
