Zanmai Day 2026 Limited Edition 33 Layer VG-10 Petty 150mm

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.

33-Layer VG10

A classic Japanese layered construction built around a VG10 core. The 33-layer Damascus-style blade combines VG10’s excellent edge retention, corrosion resistance, and ability to take a fine, keen edge with the visual character of layered steel.

The alternating layers create a subtle pattern across the blade, while the VG10 core provides the cutting performance. It is a practical combination of performance and craftsmanship, with stainless convenience and a finish that reveals the work that goes into making the blade.

A proven choice for everyday kitchen use, with a little more character than a conventional stainless blade
