I would like to discuss having a HideAway made for whitewater rescue. Your HideAway becomes an extension of the hand. In a whitewater rescue situation, this would allow swimming with the knife in hand and then application.
The tip must be blunt like an Emersen 'SARK' which is clipped to one of my rescue vests. Any maker that would like to do one would be OK with me. I have 'LaGriffes' and the single finger attachment is the problem and can allow rotation. Your HideAway does not allow rotation.
