Mako: M390 Super Steel

Austrian Böhler M390 at 60-62 HRC — hard, rust-resistant, rarely needs sharpening.

Why choose Mako M390 Knife

Most knives keep sharp within days. M390 is different.

It sharp for years. Not a week.

Reserved for ultra‑high‑end knives and machinery, it's forged via third‑gen powder metallurgy for molecular‑level carbide uniformity.

Delivering lasting sharpness, efficiency, and an unmatched cooking joy.

Sharpening only once a year

Wear-resistant: This is the biggest pain point for kitchen knives.

We push this Super Material even further with a rigorous full-blade vacuum heat treatment, deep cryogenic treatment, and triple tempering process. This carefully controlled heat treatment allows M390 to reach an impressive 60–62 HRC hardness, delivering truly exceptional edge retention.

Delicious because of sharpness.

M390 achieves an extreme hardness of HRC 62, allowing us to grind the edge down to an ultra-fine micron-level thickness. The benefit is that when processing ingredients, it minimizes cell damage and juice loss. Maintaining working rigidity at the micron level is something other steels cannot match.

Clean Cuts. Never Crush.

A smaller edge angle creates a more effortless cut. Most knives on the market use a 20° edge angle. Because of M390’s extreme hardness, it is notoriously difficult to machine with conventional equipment. Yet we went the extra mile, grinding the blade to an ultra-fine 15° edge angle, significantly reducing cutting resistance.

Deep-V Blade — Efficient Cutting

Through an extremely time-consuming six-stage water grinding process, we sculpted a smooth, continuous V-tapered geometry. While most knives only apply a V-grind at the edge, our blade features a gradual V-taper across the entire blade body. While this significantly increases manufacturing costs, it also greatly enhances your user experience.

Taste the Food, Not the Knife.

We approached this flavor problem with science. Thanks to M390’s exceptionally high chromium content, far beyond that of conventional steels, its surface naturally forms an extremely dense passivation layer. Even in harsh acidic environments, this protective barrier remains highly stable, effectively preventing the release of iron ions at the source.

Authoritative scientific experimental data

The numbers speak for themselves:

M390’s iron ion migration is only about 0.02 mg/kg — nearly one-fifth that of high-end AUS-10 steel, and far below the human taste detection threshold of 0.5 mg/kg.

This means safer food, longer knife lifespan, and easier knife maintenance.

How to pick material?

M390、VG10 and Others

M390​ — Europe's powder-metallurgy super steel. Higher hardness (60–62 HRC), extraordinary edge retention. It stays sharp far longer between sharpenings — built for those who demand peak performance.

VG10​ — Japan's legendary gold standard. Balanced, corrosion-resistant, and effortless to maintain. Easy to sharpen on a standard whetstone, a smart choice for everyday cooking.

True Full Tang design

The result isperfect weight distribution and exceptional balance, making every cut smoother, more controlled, and safer. The solid one‑piece core delivers outstanding strength and stability — it won’t flex, and it won’t fail.

Precision CNC Hollow Handle

Combined with athree‑dimensional tapered profile, refined through dozens of rounds of 3D prototype testing, and amicro‑sandblasted surfacethat creates a natural tactile grip, the handle fills your palm perfectly. Every finger naturally finds its place, delivering an unprecedented level of control.

Metal stands the test of time.

While most mass‑produced knives rely on cheap injection molding or casting, we brought Titaner’s signature CNC expertise into the kitchen. The result is flawless metal strength without the internal pores or weaknesses common in casting.

Floating Handle Design

We precisely calculated the drop height from handle to blade tang, creating a generous Knuckle Clearance zone for your hand. No matter how fast you work, no matter how close to the board you go, your fingers will never collide with the surface — letting you chop freely and confidently.

Rounded Choil: Pain-Free Pinch Grip

In mass-produced knives, to squeeze every second of machine efficiency, manufacturers often leave the spine and choil with unpolished, cold, and sharp 90° angles. This hidden compromise, made for cost-saving, can ruthlessly cut your fingers during cooking.

Rule Every Millimeter of Kitchen.

Forget those knife block sets with 15 dusty knives. A truly professional kitchen never relies on quantity. A master chef doesn’t use a hammer to turn a screw.

The MAKO 8‑6‑3.5 set isn’t just a scaled collection of sizes — it’s a highly coordinated, complete cooking ecosystem.

FAQs
