i love the original wensel woodsman head, my fave!
lotsa good ways to sharpen this fine broadhead.
mounted on a piece of shaft, i take a new woodsman and run it on a table sanding belt and slightly tip up the back end on all 3 sides to slightly reshape the too flimsy needle point into a tri-chisel shape.
then i push each side on a 12" mill bastard file to sharpen, finishing with a fine diamond stone. will shave arm hair. in my field possibles bag i take a 6" mill bastard file and folding diamond hone for touch ups.
