Maxamet vs MagnaCut: Extreme Edge vs Do-It-All


Maxamet and MagnaCut sit at opposite ends of the modern super-steel spectrum, and comparing them is really a question about what you want a knife to be. One is a specialist pushed to an extreme; the other is the best all-rounder the industry has produced. Here's the honest breakdown — and which one belongs in your pocket.

The Short Version

Maxamet (Carpenter Micro-Melt Maxamet) is a non-stainless powder tool steel that runs at a scarcely-believable 67–68 HRC in production knives. Its edge retention is the best you can buy in a factory folder, full stop. The price you pay: it will rust if you neglect it, it can chip under hard use, and sharpening it without diamond stones is an exercise in frustration.

MagnaCut (CPM MagnaCut, designed by metallurgist Larrin Thomas in 2021) is a stainless powder steel built to delete the compromise entirely: corrosion resistance better than S35VN, toughness that embarrasses most stainless steels, and edge retention in the S45VN-and-up class when run hard (62–64 HRC). It isn't the best at any single property — it's shockingly good at all of them at once.

Edge Retention: Maxamet Wins, By a Lot

In CATRA testing and real-world rope-cutting, Maxamet outlasts effectively every production steel — including MagnaCut by a wide margin. If your definition of a great blade is "cuts cardboard for months between touch-ups," nothing else in a factory knife matches it. This is the entire reason Maxamet exists.

Everything Else: MagnaCut Wins, By a Lot

Toughness is Maxamet's weak spot — at 68 HRC the edge can chip on staples, knots, or a bad cutting board angle, and field repair is slow because only diamond abrasives cut it efficiently. It also needs actual maintenance: wipe it down, oil it, don't leave it sweaty in a pocket, or it will spot. MagnaCut shrugs at all of that. It takes hard use, laughs at salt water (it's popular in fishing and dive knives for a reason), and sharpens on ordinary stones in normal time.

Availability Is Part of the Answer

MagnaCut is in everything now — Spyderco, Benchmade, CRK, Demko, Hogue, and dozens of makers run it as a standard offering. Maxamet is effectively a Spyderco specialty that appears in limited runs of the Manix 2 Lightweight, Para 3, Para Military 2, and Native 5 — and every Maxamet run in our catalog is currently sold out, which tells you how fast they move. If you want one, watch the product pages and jump when stock lands.

The verdict: MagnaCut is the right steel for almost everyone — it's tough, rustproof, easy to live with, and available in whatever knife you already want. Maxamet is the right steel for the edge-retention obsessive who maintains their blades, owns diamond stones, and wants the longest-cutting factory edge money can buy. They're both great; they're just answering different questions.
