Japanese Deba Knife 195mm minamoto Otofusa 源音房 kitchen knife

This is a 195mm Japanese Deba knife from the traditional brand Minamoto Otofusa (源音房), a respected name associated with high-quality blades from regions like Sanjo, Niigata, often crafted in Shirogami (White #2) steel for excellent sharpness and edge retention.


Designed primarily for breaking down and filleting fish, this Deba features a single-bevel edge and a robust yet tapered profile. Notably, its unusually thin spine provides exceptional versatility—it can double as a gyuto (chef's knife) for general prep or even handle precise sashimi slicing, offering more agility than typical heavier Deba knives.


The knife is unused (new old stock) but shows some surface rust due to improper long-term storage—a common issue with reactive carbon steel blades that can be easily removed with proper polishing and maintenance. Once restored, it will perform beautifully for professional or home use in seafood preparation.
