I have had my couple for a few years (2020-2021ish). New to CS knives, so i didn't focus on thinning them (previously my primary sharpening was straight razors and for planer tools working on bamboo). Mistake on my end? 100%.
What i can state is one knife has a primary bevel at 50/50, one is at a 30/70 (left edge the steeper angle). Soft fish my sujihiki does steer. And i just for the first time tried thinning/leveling the bevel. And it does seem to have high/low spots. And a lot of them. User error? Could be. I didn't focus on finish for now, but it sounds like a rustic maker.
All this said, i like them, but i would also not call them precision tools. Expensive for intro knives and maybe a touch of a chore, but honestly, I'm not sad about my first foray into carbon steel.
