What would a 3 foot two handle hay knife be valued at approximately?
I have two and are in awesome shape. Handles are original

They don't seem to bring much around here. May be $10-15.

I have one that I carried with me to flea markets for about 10 years and couldn't get $ 10.00 for it. Not even an offer.

They give new meaning to the term "wall hanger"".
BTW, for obvious reasons they are called lightning style. Check out English or European style. Yikes!

They go for $10 to $ 25 up here but thats Canadian dollers, so about 7 to 20 US. they are not something that is hard to find.

If you post a picture, I can give you an idea.  Some of the patented ones with replaceable teeth go higher.  I have sold them anywhere from 10 to 100.00, although most of the common ones go for 15-20.  Most of the earlier, single handled, knife type go for around 20-40.  The much earlier ones with the crescent shaped blades go for 50 to 75.00, although I do not see too many of those.
