Kitchen knives? My ex-wife as well as former girlfriends thought nothing of tossing my prized knives (carbon steel/wood handles) in the dishwasher or water-filled sink. Perhaps there are one in a million folks out there appreciative of 'fashion designer/hide in the attic/display in a box' (ie 10-100X beyond the use-daily price) kitchen knives but the 50-100 year old "finds" I use are all I have ever wanted.
If it's looks and outrageous price you're going for I can't help you or offer advice. Garage and Estate sales (and the Lee Valley Tools Catalogue of 1997) though will turn up the occasional Solingen, Sheffield, Swedish, Sabatier-trademark etc professional knife from before 1950 when "no-stain" became all the rage and owners didn't care about how sharp or how long an edge lasted. And that was followed by the 70's auto dishwasher crowd which made sure that plastic handles became the kitchen norm for weapon of choice.
And now folks are suddenly running out in droves to buy expensive Japanese laminated knives that have no choil or bolster! They're OK (they bend easily) but a $5 American "Old Hickory" could do exactly the same thing 40 years ago but were only ever found in Project housing, tool boxes and fishing tackleboxes at the time.
