Here's mine:





It's plate steel (16 ga., I think...I'll try to check that for you) cut out with a steel-cutting blade in a jig saw, finished on a grinder and with hand files, and riveted onto an 8' pine shaft, using nails for rivets peened over washers for roves. Steel's treated with sulfuric acid, then salt water, then burnished with 000 steel wool and oil. Total cost was about $15.00.
