For war Canoe the block can be cut to make two knee pads (top and bottom half).
Buyer must carve to custom fit knee to create fit and firm connection with the boat. A loose fitting block will decrease control of the paddler on the boat. We do not sell pre-carved knee blocks as this is a very personal fit. If you buy a foam block that is pre-carved, you will still want to customize the fit, all knees are different!
