For your information, most of the Japanese Kitchen knives come originally with double bevel edge sharpened 70/30 (face side/back side) for Western style knives. This geometry came from Japanese Traditional knives with single bevel edge and Shinogi blade construction. This is one of the special features and reasons why Japanese knives have an excellent cutting performance.

However, this 70/30 edge geometry is designed for right hand use, so we have a service to modify it to 30/70 for left handed users with re-sharpening process by skilled craftsman.

We believe quality and performance of Japanese knives are best in the world and hope you enjoy the fine craftsmanship and spirits from your new knife. With proper cares, every Japanese knife can be your special cooking partner for a long time.

    Confidence inspiring customer service

    First off, the knife is perfect, it was a gift for my mother and she is beyond pleased. It is razor sharp and the fit and finish is flawless. Also, the best price I could find. More to the point, there was a hiccup with the delivery from DHL where they informed me it had been delivered when it had not. It was too late to call DHL that night, but I sent a heads up email to the seller, not expecting them to do anything, but wanting to let them know as early as possible in case there was a real problem. The next morning when I woke up I already had a reply from Koki saying they were looking into it on their end, and when I called DHL they were aware of the issue and had already opened a case. Long story short, the knife showed up the next day, no big deal, but I'm very confident that if there had been a real issue it would have been resolved promptly and fairly. This also happened the first day back from their Golden Week vacation so I'm sure they had a thousand emails to deal with. Overall both pleased and impressed.

    Masamoto Vg Santoku

    This is by far the one of the best knives i have ever owned. Sharp straight out of the box, and I’ve been using it heavily for the past 3 weeks without any noticeable dulling!
