Just want to thank those that contributed the good, the bad and the ugly to this thread. It helped in my decision making to buy from an authorized dealer for warrantee purposes. The Chi below will join my rotation of EDC's and want to see if this super steel will really hold its edge for 2 - 3 years. So far I can say its an easy to carry, has a great fit and finish small knife with a smooth slicing edge. The jury is out and time will tell.

Nice knife, but it won’t hold an edge for 2-3 years unless you just open envelopes.

That my feeling as well. Im pretty easy on knives but most dull pretty quickly, that was the appealing part of buying one other than how beautiful they are. Their edge geometry seems tricky to re-sharpen on a wheel or wicked edge so Ill ship it back to Japan and have them regrind it when its beyond stropping touch-ups.

You have a Chi which has Shinogizukuri grind, it’s not convex; flat Sabre grind with a big edge bevel. You can simply touch up the edge on a sharp maker.

hello Rockstead experts. i have a question (apologies if it was answered in this 91 page thread, but reading the last 6-7 has sapped my will to read any further. too much tribalism):

any reason why the Hizen doesn't have a zero-convex like the bigger brother, the Higo? i mean, the whole reason why i got attracted by the brand was the fancy mirror zero grind, and then when i found out the Hizen, which would suit my EDC needs (already tried blades in the Higo size, too big for me), it has a "normal" secondary bevel (though mirror polished), kinda defeating the purpose...

Nothing a regrind wouldn't fix;)

It’s just what they decided to use, that simple. It’s also not just a “normal” secondary bevel. The shinogizukuri grind is not convex in any way on either bevel.

well, yeah... but that complicates things quite a bit, not to mention it makes it significantly more expensive for a peasant from Europe like me :D

yeah, that's my point. it's not convex in a any way. to me, that'd be kinda like a bark river with a flat grind. it just loses a huge part of the appeal. i get it that it's not "normal" because it goes from 30 to 24 degrees so it's not exactly flat flat, obviously. but still :(

i wonder if they'd do a honzukuri Hizen if requested :D or resign myself to saving up twice as much money for the (to me) less attractive Shu :eek:

Oh no, Shinogizukuri is flat flat. Only Honzukuri is convex and has the differential angle. That said, I highly doubt that they would take a special request since they are made by CNC. Only the polishing is done by hand, and I believe even the end finishing is actually an automated process.
