Sakai Takayuki INOX Stainless Baran-kiri Single Bevel Petty 120mm

A petty knife is a small Japanese utility knife, typically with a blade between 120mm and 180mm, designed for precision tasks like peeling, trimming, and slicing fruits and vegetables. You need one when your main chef’s knife feels too large for detail work, think deveining shrimp, cutting garnishes, or any in-hand peeling where a bigger blade gets in the way. Its slightly longer and slimmer profile than a Western paring knife gives you more control for intricate cuts without sacrificing the nimble feel you want for small jobs. If you regularly find yourself reaching for a smaller blade for finishing work, a petty fills that gap cleanly.

A petty is not a replacement for a gyuto or santoku. It lacks the blade length and belly for efficient chopping, rocking, or breaking down larger proteins. If your work is mostly bulk prep, like dicing onions or slicing roasts, a petty will feel slow and underpowered. It also won’t handle heavy tasks like splitting bones or prying, so treat it as a precision tool, not an all-rounder.

The petty’s role in a Japanese kitchen is as the smaller counterpart to the gyuto, built for tasks where a full-size blade is clumsy. At Knives and Stones, the petty category covers a range of steels including VG10, White#2, Swedish Steel, VG5, SG2, and MV, from makers like Sakai Takayuki, Masamoto Sohonten, Ryusen, Nigara, Hatsukokoro, and Sentan. Most are double-beveled, and the blade length runs from 120mm to 180mm, which is what gives it that balance of reach and precision.

Inox is French, short for inoxydable (acier inoxydable), the French words for stainless steel.

So the word on a blade says stainless steel, not which grade or brand. Stainless steel strictly means a steel that rusts less, so dry the knife after washing.

Sakai Takayuki (堺孝行) is a brand of Aoki Hamono Seisakusho (青木刃物製作所) in Sakai, Osaka, and the company's own page says so directly. The trademarks for 堺孝行 and 堺菊孝 were registered in 1964.

The company started in Tondabayashi, Osaka, in 1947 as a wholesaler of Sakai forged knives, moved its office to Sakai in 1963, and built its Sanpo factory in Sakai in 1977. So when you see the Sakai Takayuki name, that is Aoki Hamono's own line.

Sakai Takayuki knives are made by Aoki Hamono Seisakusho and its craftsmen in Sakai, Osaka. The company's own traditional-craftsman page profiles its named Sakai smiths.

Sakai works by division of labour: forging, grinding and sharpening are each done by a different specialist. Aoki Hamono's Sanpo factory, home to its smiths and sharpeners since 1978, added an automatic grinding machine for Japanese knives in 2015.

A honyaki is water quenched with sword-style hardening, so it usually runs about 1 to 2 HRC harder than a comparable knife that is not honyaki, though that varies by maker. The quench has a high failure rate, and that craft is a large part of the price.

A honyaki also needs more care. If your kitchen is busy, an everyday line such as the 33-layer or 45-layer VG10 Damascus, which share a VG10 core and differ mostly in looks, is the easier choice; if you want a harder edge and the craft itself, a honyaki can suit you.
