A hydroblade is a figure skating edge move or connecting step in which a skater glides on a deep edge with the body stretched in a very low position, almost touching the ice. Several variations in position are possible, but one commonly performed by singles skaters is on a back inside edge with the knee of the skating leg deeply bent, the free leg crossed behind and extended outside the circle, and the upper body leaning into the circle with two, one, or no hands skimming the ice.
