I found this modified chisel in an auction box. The end has been rounded and it has been curved through its' length. The only thing I can think of is a digging tool for use with a metal detector. It's 1 1/2" wide x 3" long.
Timber framing gouge. Used for fitting logs/timbers; I have a few that are much larger, with a 12" blade and 12" handle you get great leverage and control on paring cuts.
