![]() This was found in a N. Ga barn. There are no impact marks on the heel, and the "edge" is not nor has ever been sharpened. The loop is centered axially. It looks to be either cast iron/steel, or drop forged judging by the "seam". I have only had a chance to photo this; spark test would be next, unless one of ya'll can ID this: http://bellsouthpwp.net/m/o/molly9/target0.html Thanks! ~Dave, Demo Smith Red Top Mtn.

State Park http://gastateparks.org/net/go/parks...id=21&siteid=5 A wedge to prevent binding when cross cut sawing timber, it is pounded into the kerf behind the saw blade before or as soon as it starts to close up. You can actually see the timber bow upward as the kerf is opened up. The loop is there to attach a wire on the other end of which is tied a brightly coloured rag to help locate the wedge when it is dropped in deep snow etc. Wedges for chain saw work are normally made of aluminium, since the operator has much less control, and things happen a lot faster and more expensively.

Actually, many faller's wedges are made of plastic nowdays. I dunno. If it's a fallers wedge, or a kerf wedge, it is "New, Out of Barn". No hammermarks on the heel. The concept of the loop for a marker rag adds to the novelty. Textile industry machine piece is a possibility, FWIW. My guess, only. Please, keep playing! ~Dave |

Gerry nailed it first time. It's a kerf wedge. A felling wedge is thicker. There are no hammer marks because the kerf wedge was always driven by wooden mall or beetle. The eyelet was used to tie off the wedge so it would not fall as the kerf opened, a valuable asset when used with a saw pit, as a falling wedge could easily become a "widow maker" if it struck the "under dog" as the pit sawyer was called. -- The Road Warrior Hobbit |

i was in china in 1982, i witnessed with my own eyes two guys sawing a huge
log into a beam for a temple that had been destroyed during the cultural revolution. i was astounded to see (two) human power being employed to rip saw a log. (this wasn't just a "historical re-creation" either, it seemed to me the government wouldn't allocate funds (electricity) to rebuild this temple, it was in the south and i had the impression it was an islamic temple). one guy standing on the log, the log in a wood cradle, one guy in a pit below. that's hard work huh? i guess they'd be EXPERTS in saw sharpening. never considered that possibility, a kerf wedge falling on some guy's head. ouch. you'd think they could just as easily used a wooden wedge though huh? b.w. (also rode on steam powered trains, that was totally awesome too! they truly did seem like living things, steam and fire breathing dragons hauling these long streams of rail cars.)
