About Moritaka Hamono -Moritaka Hamono was founded in 1293 and have been producing high quality blades for 31 generations. I think they know what they’re doing by now. Five generations ago the family made the switch to producing only Hocho (kitchen knives).The knives made by the Moritaka family have a real classiness and beauty. This series of knives are known for a thinness which translates to fantastic sharpness.

If you want one knife to do it all, and look cooler than your buddy, this is your knife. For the at-home or professional cook, we recommend a Kiritsuke which measures between 210mm and 240mm long.
