A 75mm petty is about as small as a kitchen knife gets, and this one from the Masakage Koishi line is built specifically for in hand work like turning potatoes, peeling small fruit, or trimming cheese. The Koishi line is the top of the line offering from Masakage, handmade by Yoshimi Kato using Aogami Super steel.
Aogami Super is a highly renowned carbon steel, valued for its ability to take and hold an incredibly sharp edge, and this petty is hardened to around 63 to 65 HRC, making it one of the hardest blades in the Masakage catalog. The core is clad in a stainless steel kurouchi finish with a dimpled, pebble like hammer texture, which is exactly where the Koishi name comes from, since koishi means pebbles in Japanese. The handle is an octagonal cherry wood with a black pakka wood ferrule.
What Customers Are Saying:Owners who have had this petty for years still call it the best in hand knife they own, citing edge retention, classic looks, and a great feel as the reasons they keep reaching for it. More than one reviewer notes that the kurouchi finish makes cleanup and care simple, and that sharpenability and edge retention are well above what they expected at this size.
Care Instructions:Aogami Super is reactive and among the hardest carbon steels available, so wipe and dry the blade immediately after each use rather than letting it sit. Avoid leaving acidic foods against the blade for long stretches, and apply a light coat of camellia oil for longer term storage. Hand wash only, and because AS holds an edge so well, a quality water stone with a final strop will keep it performing at its sharpest between full sharpenings.

$184 for a paring knife? Yes. All day long. This knife is nothing short of perfect for in-hand work. The kurouchi finish makes cleanup and care a breeze. Sharpen-ability and edge retention are off the charts! I couldn't be happier.

The best out of hundreds of pettys handled.
