Microtech Santoku 4.2" – a compact kitchen knife with a titanium bolster

Microtech Santoku 4.2" Titanium Bolster / Caribbean Blue G10, Stonewashed M390MK (3300B-10CA) is a modern interpretation of a short Santoku-style kitchen knife, crafted by a brand known for its technical precision and high-quality workmanship. The model features a blade made of Böhler M390MK steel, a flat grind, a Stonewashed finish, and a G10 composite handle supported by a titanium bolster. This tool is designed for precise slicing, chopping, and portioning of smaller ingredients.

The Caribbean Blue / Gray variant gives the design a fresh, modern character while maintaining Microtech’s minimalist design language. The shorter Santoku blade is ideal for working with vegetables, herbs, fruits, smaller portions of meat, and ingredients that require precise blade control. The included blade guard facilitates safe storage and transport, especially outside the traditional kitchen knife block.

Böhler M390MK – Microtech Powder Steel in a Kitchen Knife

Böhler M390MK is a special grade of M390 steel developed for Microtech in collaboration with Böhler, designed with an emphasis on wear resistance, corrosion resistance, and long-lasting sharpness. In a kitchen knife, this means a stable cutting edge even with frequent contact with moisture, cutting boards, food juices, and ingredients of varying textures.

In the 4.2" Santoku model, M390MK steel is well-suited for tasks requiring precision: thinly slicing vegetables, chopping herbs, portioning small ingredients, and working on a limited cutting board surface. With proper care, this material maintains high cutting performance for a long time, reducing the frequency of sharpening compared to many standard kitchen steels.

Santoku Profile and Flat Grind – Control with a Shorter Blade

The Santoku profile is designed for versatile kitchen work, especially where control, consistent movement, and precise blade guidance are essential. The compact blade length makes it easier to work with smaller ingredients, and the distinctive blade profile works well for slicing, chopping, and portioning.

The flat grind ensures the blade glides smoothly through the food, minimizing resistance during cutting. The Stonewashed finish gives the blade a matte, industrial look and helps mask minor signs of regular use. As a result, the knife retains its professional character even with frequent use in home or commercial kitchens.

Caribbean Blue G10 and Titanium Bolster – Ergonomics and Durability

The handle, made of G10 / Titanium, combines the durability of the composite material with the elegant, technical accent of the titanium bolster. G10 withstands moisture, temperature fluctuations, and mechanical stress well, making it ideal for kitchen environments where the handle is regularly exposed to water, steam, and intense hand movement.

The Caribbean Blue / Gray color gives the knife a distinctive yet professional look. The handle’s subtle texture promotes a more secure grip, while the Torx screw assembly reinforces the design’s technical character. The short Santoku format facilitates control during precise work, minimizing hand fatigue during extended food preparation.
