I have an 8" long three line Swaty hone that I've had for quite a while. Its top is intact and the bottom has one shallow chip that does not interfere with honing. Someone is looking to buy one and I am considering selling it. I consider a fair price for a normal sized, lapped and shipped Swaty to be in the range of $30-40 though I fully realize that one can take a shot on ebay and potentially get them cheaper.

I would like to get input from the collective regarding the value of the long version of the Swaty. I don't know how rare they are but mine is the only one I have seen. I have a value in mind but I would like to know what others think. So, what's it worth?
