What is it?

Not the one with George's picture on it...the other one. Spark tests high carbon. Bought a small box full at estate sale.

Some sort of drift pin, perhaps? Does the tip come to a point like a nail or a blade like a chisel? Have you done a file test?

Looks almost like a wedge to go with feathers for splitting stone. Big stone.

Harrow spike used to break up dirt clods after plowing. High Carbon to resist abrasion

as in "The toad beneath the harrow knows exactly where each tooth-point goes"

was the auction in farm country?

Looks like harrow teeth to me. A harrow is a ground tillage tool used to break up clods of dirt and level/smooth the ground.

I kind of suspected harrow tooth. Pointed four sides like a spike. Thanks. Bart

"Spike Tooth Harrows" are also used to groom Race Tracks .....

I don't think that it is a harrow tooth- they are headless and have chizel-cut barbs on the top (unpointed end) to hold them in the wooden stock. It may be a stone mason's pointer.

Not all are headless and barbed. http://www.speeco.com/products.php?id=45&id2=52&prod=32

Good call DKlunker. Good sized harrie though. Post above you would be right too though. Ole timey wood harrie is different. I've pulled a 14' fold out for a few hours. Headed teeth but smaller than the ones starting this thread.
