I have a similar item listed in the upcoming Wrenching News Auction in April (Lot 754-4 just to the left of the rusty hammer). I think it is cast iron. Would it also be a log dog?

It looks factory made, but yes I think it's a log dog. It is certainly not for tethering your horse, but the one below that "strange" handled hammer is! What is 755(3)?

I agree that the ring below the hammer is a horse hitch ring. The first item in Lot 755 is marked: LAWSON-LAUGHLIN SPECIIATY CO. - CHICAGO, ILL - PAT'D MAY 12, 1908. It's 11" long and is a meat tenderizer marketed as the "Sanitary Steak Shreader". Patented by Richard Lawson of Effinghan, Illinois. I found the patent at:
