Specifications

The Masahiro Atama Otoshi is a specialized 235mm fish fillet knife from Seki, Japan, designed for processing large fish like mahi-mahi and tuna. Crafted from proprietary MBS26 stainless steel (~59 HRC), its monosteel construction offers durability at a lighter weight (238g) than traditional Deba knives. The 80:20 edge bevel and tapered spine (2.7mm to 1.6mm) provide precision for Okinawan fish-butchery techniques.

FAQ

Why is the blade length different from the displayed size? The size in the product title is a nominal reference used by knife makers. The actual blade can be slightly longer or shorter due to handcrafting and traditional sizing. Each product page lists the exact measured length.

When will out-of-stock items be restocked? We carry limited, rotating stock. Once something sells out, we don't necessarily reorder it right away. It could be months before that item comes back, if at all. We bring in new knives regularly, but they're not always the same ones. Our newsletter is the best way to stay updated on new arrivals.

What payment methods do you accept? Visa, Mastercard, Amex, PayPal, Apple Pay, Google Pay, and Shop Pay. No cash on delivery.
