Underwater kinetics Remora Hydralloy Knife

The non-corroding Remora™ HYDRALLOY® BC knife is the one emergency knife all divers should wear. Small size, attachments for belt, hose or fabric, and no maintenance design make the Remora the emergency knife for all divers.

Previously, there was not a commercially available stainless steel which had a combination of being hard enough to maintain an edge, yet stiff enough for prying, and did not rust in salt water.

Our constant quest for perfection leads us to develop a special alloy that combines the best qualities of 316 and 420 steel to produce corrosion-resistant blades with great strength and sharpness. We now do custom mill runs of our proprietary steel formula, which not only has different alloy content but also a different heat treating process than other dive knives, making UK knives unique in their performance.
