So, curiosity got the best of me and I just checked, the guy still has the Japanese woodblock prints he also collected for sale, so I'd assume he still has a few thousand of the knives. I just reached out to him and might swing by again (for the woodblock print). I remember each drawer in these tool boxes being literally crammed full, so I could likely have missed something cool. If I go back, I'll look thru again and maybe pick up a few more if I find some decent ones. Nearly all of them were French chef's knives or American of cheaper style. If I find anything decent, I might consider doing a proxy buy, selling them for a tiny markup for my time.
Way, way buried in the back of his garage was a wooden cabinet with some very old unopened bottles of booze. I told him at the time that I was interested in those!
