Don't have pics, but mine is made out a model T axle. Welded on a 3/4 inch plate steel to end about 1 1/2 inch wide and sharpened so it would be an inverted V. I like it - balanced, not to heavy to carry around yet enough weight to help chopping a hole.
Only thing I would change on it would be to weld another piece of metal to the upper end so it couldn't slip through my hands. Or maybe drill a hole and thread a cord thru it to go around my wrist. Been doing fine all these years though, more than likely will leave well enough alone.
OK, I'll fess up. It was my father's who made it back in the 30's and used it the rest of his life. I got it in in 1995 when he moved on to the big shanty and haven't found or saw anything better. Still using some of his tip-ups when the grandchildren come along.
