A laminated hockey stick is kind made like plywood. Strips of wood are glued together. However, a stick is normally tougher than plywood, IMO. The stick is square though, so if you want it rounded, you will need a file and some effort and patience. I played a lot of hockey and saw few sticks broken in the middle, while many blades break.
As far as a hiking staff, a hockey stick might be a too short, if you are tall. At full length, one comes to my chest.
