There's a guy named Ralph who has a store on eBay. He specializes in knives, many of them vintage carbon steel. I've ordered a couple from him; they were exactly as described, and the transaction was smooth with no glitches. He handles everything from mass market inexpensive knives all the way up to items in the four figures. You might check out his inventory at the link.

Also, doing an eBay search for 'vintage carbon steel knives' will usually bring up some results--however, lots of people in cyberspace like these knives as well so expect the bidding to be spirited (i.e., don't expect bargains).

I got hooked on carbon steel knives when I acquired a bunch of them at a yard sale. Great stuff, and I greatly prefer them for cutting anything non-acidic.
