Please note, these can have cosmetic scratches or small imperfections in handles which will not impede the performance of the knife. This is par for the course on these knives and is part of how they sell them for a very reasonable price. We have been very happy with the quality for the price and their old style country feel.

Katsuo bocho are designed for quickly and efficiently breaking down skipjack tuna also known as bonito or katsuo, an important fish in Japanese cuisine and a staple of Shikoku’s fisheries. Bonito swim past Shikoku several times a year and the region is famous for it’s dried and smoked katsuoboshi and fresh bonito.

This knife is great for this style of fish breaking which avoids the thick bones unlike a deba as well as being great for other proteins both raw and cooked.

This is a reactive carbon steel. It should be mentioned that extra care is required, as the knife is not stainless and should be dried immediately after use. It will develop a dark patina with usage, but any orange rust should be removed with a light abrasive.
