I couldn't sell my Gaffi stick so I'm going to make proper steel blades and have them welded on and a spike. My spike is wood and looks okay, but I figure I might as well go all out. Does anyone have a source for a similar spike that is steel? I don't have an angle grinder or anything suitable to cut a chunk of metal that thick (safely anyway), so I don't think I could make one. My tube is 1" diameter, so I'm guessing the inner diameter is probably 3/4".
