Hacksaw - I made a real nice improvised axe handle out of one once. It worked so well that I never bothered to buy a replacement handle for the one I broke.
I can see a laminated shaft from a hockey stick as the handle for almost any and every tool, from a shovel, ax, pick ax, hoe, post-holer digger, etc., etc. etc.
I can also see them being used as building material for a lot of things.
At near the same size, their cannot be many stonger pieces of wood than a laminated hockey stick.
