These rules do not apply to the goalie stick. According to rule 20 sec.c for goalies there is to be no measurement of the curvature . Blade curvature is personal among hockey players and each have their own guidelines and ways of bending their blades. It seems though that all the young players want the big curve. There are plenty of ways to get the bow in a stick blade , some of which border on the absurd.
Most players heat up the blade with a torch then bend it somehow.
After bending the blade it is quickly cooled into form. Guys will dunk it in a bucket of ice, but some players are superstitious and I ve even heard of players cooling their sticks in the toilet , Christian said. For all the attention given to blade curvature there is a general feeling of apathy towards the applicable rules. It's it s not something we really look for . The stick gauge is an aluminum device that attaches to the heel and toe of a stick blade with a sliding gauge to measure the bend.
