Never again will you lose an edge in practise. Never again will you wreck a fresh sharpenning by hitting the post with your blades in the warm-up and have to play a whole game on one edge. The Edge ProTECH is the answer. Designed by goalies, for goalies, with a snap and a twist these slide easily on and off the posts covering the lower portion where you always ding your blades. Used by countless goalie school and pro teams it is a must for any goalie.
