Design
The Xinzuo 8.5" Bunka Octagonal is built around 67-layer damascus vg10 at 61-62 HRC, paired with a ebony wood handle. Featuring a traditional octagonal handle, this extended 8.5-inch Bunka provides a professional reach and a classic feel for serious chefs. The blade profile is a proper bunka — tall and flat for clean push cuts on the board.
Edge retention
67-layer Damascus 10Cr15CoMoV run at 61-62 HRC is a sensible target for this style of knife — hard enough to hold a fine edge through weeks of use, forgiving enough to touch up on a ceramic rod or 1000/6000 stone without micro-chipping. Expect a strop every couple of weeks with daily use and a full stone session every few months.
Ergonomics
The ebony wood handle is comfortable in either hand, with a balance point that sits right around the bolster for a neutral pinch grip. The spine and choil are eased so long prep sessions don't leave hot spots, and the 8.5" blade length is a solid all-round choice for the bunka format.
Value
At around $135 shipped, this competes with mid-tier Japanese-branded bunkas that cost roughly double, and the fit and finish holds up to the comparison. You're paying for the steel, the cladding, and a real ebony wood handle — not a stamped blade with a plastic grip. As with most factory grinds in this bracket, a short session on a stone taking the edge down to a finer angle makes it noticeably sharper.
