Abstract: A surgical saw blade comprises a cutting edge, blade body and hub for connecting the blade body to a handpiece. The cutting edge comprises two rows of cutting teeth. Each tooth has a face and an opposing hollow trough at the base thereof, the distal end of the trough terminating at beveled sides. The beveled sides and face opposing the hollow trough terminate at a cutting point. The hollow trough and cutting point combine to provide a straight, fast and accurate cut with no cutting debris build up. The dispersion of cutting debris dramatically reduces the danger of thermal necrosis, produces a cooler cut and extends the saw blade life.

Abstract: An ice barrier for the wet storage of boats is formed of a plurality of notched, elongated elements bridled about a boat hull at waterline. These elements are compressible and their outside surfaces form a V-type groove parallel to and located at the boat's waterline. In this manner, forming ice engages the elements in the notched regions and tends to lock them at that level so that they are not easily dislodged from their protective position. Any movement of the elements with the natural rocking of the boat, cooperating with the notch, aids in breaking the ice.
