assorted old iron tools/prybars/etc. #2

Can't really say this one is/was intended to be a 'prybar', but that's all I've really known it to be occasionally used for. (or to help bust up a concrete sidewalk, or whatever)

It's pictured here on the same truck tailgate for size reference but is not a recent acquisition -- this tool actually lived in my Dad's garage for nearly my whole life until I reclaimed it for my own during their big 'downsize/move' several years ago now -- I otherwise came across it again today while finding the corner in my toolshed to stick the other two smaller(ish) ones just shown. (and the biggest one next to come, if I last that long tonite?)

One end is squared with a thru-hole, the other is rounded/pointed (but not quite "tapered"?) with an extra little 'ridge/ring' cast into it a few inches up from that end, also what looks like a small 'slot' milled lengthways into it on that end, which looks now (when I was taking the pics) like it probably is still full of that 'old sidewalk' remains mentioned earlier... ;-)

Once more, no markings I can find anywhere on it, and suggestions MORE THAN WELCOMED if anybody does recognize what this thing was really intended to be/do! :-) :-) :-)
