Our Story

Seisuke Knife's mission is to introduce Japanese culture and traditional craftsmanship to customers by selling high quality Japanese knives. To us, a kitchen knife is more than just a simple tool to cut food, but an art piece that a craftsman puts their heart & soul into.

Our store opened in 2016 in the Alberta Arts District in the heart of NE Portland, OR. We display a variety of knives from some of the most revered knife craftsmen in the Japanese knife industry. Knives from Yu Kurosaki, Yoshimi Kato, & Nao Yamamoto just to name a few. Stop by the store for a chance experience the lightweight feel & silky sharpness.

Large Selection

We boast a robust selection of high quality knives imported from Japan. From inexpensive everyday cutlery to beautifully hand-forged knives, we're sure to have the perfect knife for you! 

Friendly, Knowledgeable Staff

Stop by our shop in Portland, Oregon and let a member of our staff help you find the perfect knife for you. With years of experience working with knives, they know the practical differences between the knives and will help you narrow down our vast selection. 

Sharpening Services

Our sharpeners have years of experience and can give you the best edge on your knife. We offer a variety of repair services to skillfully restore your knife to its former glory. 

Our Portland Team

Since 2016, the team has been sharing their love and knowledge of Japanese kitchen knives to Portland, Oregon.

Sales & Sharpening




Every year we celebrate the anniversary of our opening by inviting some of the craftsmen we work with to Portland. Meet the makers behind the knives, and give them a chance to get some feedback on their work.

Plan on stopping by during our next anniversary, to chat, get an extra discount, and maybe even catch a knife forging demonstration.
