I'd been curious about Yoshikane for a while and finally pulled the trigger during Cutlery & More's July 4th sale. No regrets.
The grind is the reason to buy this. It's thin behind the edge but doesn't feel delicate, and it releases food well. Dense stuff like carrots and sweet potato splits cleanly instead of cracking apart on you. I push cut for almost everything and this thing loves that. That said, I'm still getting used to the 50mm blade height. It came sharp out of the box, and the SKD12 has held on since. I did notice some very minor edge damage at one point, but a few minutes of stropping cleared it up, so it had rolled rather than chipped.
I went with a bunka instead of the santoku in this same line specifically for the k-tip. If you do a lot of finer work, scoring, detail cuts, anything where you want to know exactly where your point is, the flat tip is worth it.
Since the handle is smooth rather than textured I wondered if it'd get slick, but it hasn't, even with wet hands. It isn't cheap for 165mm, but the fit and finish and the way it cuts justify it. It's not leaving my rail.
