Nenohi Hon-Kasumi Blue Ai Deba 165mm Ebony Handle (Mirror Polished)


Nenohi Cutlery is a venerated company in Tokyo carrying Western style knives under Nenox and Japanese style blades under Nenohi. Their single bevel Japanese knives are crafted from high quality white and blue carbon steels, known for their level of high fit and finish, great in-hand feel and suitability for high workload professional kitchens.

Nenohi Hon-Kasumi (‘Premier’ Kasumi series) knives constructed from blue steel are excellent blades for professional kitchens thanks to their high fit and finish and their ability to stay sharp for extended periods of time. Sharpening will take a little more time and patience, but thanks to the remarkably thin and consistent ura line on the flat side, it will still be an enjoyable endeavour. We recommend this to professional or avid home sushi enthusiasts looking for a single-bevel knife that does not compromise on steel quality or fit and finish.

‘Kasumi’ here refers to the opaque, milky-white finish on the flat of the blade some describe as mist-like. It will fade with repeated use and sharpening over time, not to worry. Touch it up with Tosho’s in-house Kasumi powder when you wish to restore its original luster.

An Ai Deba is a Japanese fish fileting/butchery knife that is thinner and lighter in weight than a traditional Deba. Despite its Santoku-like profile, it does not perform well on dense produce; however, it excels in deboning various fish, thanks to its weight and bevel shape. The technique of using a deba is quite different from using a flexible fileting knife (Western style fish deboning), but in practiced hands, both styles can yield very good results. We recommend a deba for any cook looking to get better at fileting fish and sharpening a single bevel knife in Japanese fashion.
