10" x 2.15" x 1" (Blade 5")


The Blue Tang HYDRALLOY is UK’s improved take on the classic, multi-functional dive knife. We patented our own HYDRALLOY steel for a blade that is both strong and corrosion resistant where most competitors’ blades only offer one of those features.

The fifth generation Hydralloy is now stronger than ever. 

The Blue Tang® HYDRALLOY® knife is built rugged, with a serrated edge and a hooked edge for cutting through all types of rope and line. It is the ultimate safety tool.
