About Goh Umanosuke Yoshihiro 郷右馬允義弘 / Yamawaki 山脇

Established in 1927 in Sakai Japan, Yamawaki Hamono produces knives under the "Yoshihiro" and "Goh Umanosuke Yoshihiro" brands, named after a famous swordsmith of the Kamakura period. Having mastered mizu-Honyaki process, the most challenging construction and treatment, Yamawaki Hamono combines Sakai's centuries-long history of knife making knowhow with newer technologies to create superior chef knives. The current owner of the Yamawaki Hamono - Mr. Ryoyo Yamawaki - is also a lecturer at several culinary schools. Having apprenticed under Sakai blacksmiths, the new generation craftsmen Igarashi Nori and Masaya Shimizu lead the Yamawaki workshop to create incredible knives that are well recognised among Sakai artisans.

Care:

Aogami #2 (Blue #2) steel is a premium Japanese high carbon steel for knife making. Despite some corrosion resistant quality (for a carbon steel), it is not stainless, therefore you should wipe your knife dry after each use. Patina will develop over time. Rust may develop if left in prolonged contact with water or acidic food. Use a rust eraser to clean if rusts develop. Avoid cutting into bones, frozen foods, hard fruit pits.

Cutting Surface:

Recommended cutting surface: wood, rubberized boards and high-end composites, and quality plastics such as polyethene make acceptable cutting surfaces, and will help protect and prolong knife’s edge. AVOID glass, metal, countertops, and other rigid, non-forgiving surfaces.

Sharpening:

We recommend sharpening all quality Japanese knives on whetstones, as we believe they yield the best results for your knives.

Surprisingly wide enough
Size: 9, Color: Black
Was surprised that they're wide enough. Usually, shoes that say they're wide, aren't really wide. They're very cute and "hopefully" when I do wear them out, they'll continue to stay comfortable. I ordered both the Coffee Bean and Black, size 9. Usually wear a 9 or 9 1/2, the fit has plenty of room in the toe area with size 9.

Cute but Ouch
Size: 8.5, Color: Sand
Theses shoes are cute and comfortable to walk in *comfortable to the soles of your feet* HOWEVER, there is part of the inside seem on the outer right ankle that scrapes my leg with every step. I tried to see if wearing them down would help, wearing band-aids, putting duct tape on my leg, mole skin - but nothing helps, by the end of the work day I still feel that scraping seem. And I'm not usually sensitive to this kind of thing. I'm way outside my return window, so I'll have to pass them along to someone else with my same shoe size or donate them. Overall they're a good shoe - i just think mine had an issue when the seems were finished

Size down 0.5!
Size: 8, Color: Black Lizard
Love the black snake skin look, I normally wear a size 8 and these fit more like an 8.5. Works with a thicker sock but I definitely recommend sizing down 0.5.
