I use the Ken Onion Worksharp and a Beavercraft ash wood handle leather strop with some simple chromium oxide compound. I can get any knife from dull to shaving sharp in 5 minutes with that set up. Do some anons here actually use whetstones here and is it really worth the effort and time you have to put into it? I remember starting out on a 1000/6000 grit double stone and it would take me at least half an hour per knife to get it shaving sharp and that was with normal 58ish HRC stainless steel kitchen knives. It'd be unthinkable to try and get a hair popping edge on some hard powder steels like M390 with those.
