yeah, I was looking at the antique ones. A similar woodworking chisel of the same period is 1/4 the price. I get the "scarcity" issue, but sheesh.... I saw one for sale for $300 and the seller was not even sure if it was a button hole chisel and the age, but "ones like this sell for up to $500" it's just silly.
Usually a high price on something like this (or featherweights) that does not merit it by materials, is driven up by collectors, but I do not see a big market for these.
New to me, just askin...
