Zanmai Day 2026 Limited Edition Rainbow V-Toku Gyuto 210mm

Mcusta Zanmai is a subset of Marusho Industry Inc. and, to this day, is a family business. The current president, Tomohiro Hasegawa took over from his father recently and together they have been at the forefront of modernizing Japanese knife making with the latest machines and modern material while maintaining age-old Japanese traditions. Their knives are laser-cut, hand assembled and hand finished to ensure near perfection.
As the Elder Hasegawa-San puts it, "...our master craftsmen infuse all our products with the pride and traditions inherited from centuries of Japanese blade makers"

In September 2026 we were lucky enough to welcome Tomo to the shop for our annual Zanmai day.

These knives are wysiwyg (what you see is what you get) - only one piece available per knife. 

Mcusta ONE

A new limited edition from Mcusta, the ONE line brings together everything we’ve come to appreciate about this small workshop in Seki City. Clean lines, thoughtful proportions, and an almost obsessive attention to detail.

Each knife is made in Japan with Mcusta’s distinctive approach to construction, combining traditional Japanese craftsmanship with modern materials and precision manufacturing. The result is a knife that feels considered in the hand and quietly refined in every detail.

The ONE is a limited run, made in small quantities and available for a short time. For those who have followed Mcusta over the years, this is a particularly nice one to add to the collection.

V-Toku Steel

V-Toku, or V-Toku 1, is a Japanese carbon steel valued for its ability to take an exceptionally fine, keen edge. It has a simple, responsive character that makes it particularly enjoyable to sharpen and work with.

The steel offers excellent edge performance and a crisp cutting feel, with the trade-off of being reactive. It will develop patina with use and requires a little more care than stainless steel.

For those who enjoy traditional Japanese carbon steels, V-Toku is a wonderfully straightforward steel. Easy to sharpen, capable of a very fine edge, and full of character as it ages.

V-toku is not a stainless steel. Proper care is needed to ensure a long lasting finish. Please wipe down and dry after each use to ensure a lifetime of use.
