Wax
During the New England Sports Network TV Show "Be A Bruin" with Johnny Bucyk and Terry O'Reilly, Bucyk was seen talking to one of the kids who was working on his blade. When the kid pulled out the wax for the blade, Bucyk made fun of him for using wax. Personally, I've never used it, as it seems you don't want the puck to slide OFF your stick most times. I was happy to see The Cheif have my back on this, since nearly all my buddies wax their sticks too.
