AEB-L Steel Knife Blade Blanks
AEB-L started life as a razor blade steel at Uddeholm, and that history explains everything about it. The alloy is deliberately lean — less chromium and carbon than most stainless knife steels — which produces an exceptionally fine, even grain structure.
We run AEB-L at 60 HRC. Fine grain means the edge can be taken thinner at the apex without the microscopic tearing that coarser steels suffer during sharpening. The result is a keenness that steels with better datasheet numbers cannot match.

Strengths: Takes a very keen edge, is tough for its hardness and sharpens easily.
Trade-off: Lower wear resistance than the powder steels.
Why kitchen knife makers choose it
If you care how a blade feels going through a ripe tomato, this is the steel. It also sharpens more easily than 60 HRC suggests, again because of the grain — there are no large carbides to fight. Corrosion resistance is good, a little behind N690 but well within what a kitchen knife needs.
Where it gives ground is abrasive wear. In rope, cardboard or dirty work AEB-L dulls sooner than the powder steels. For food on a wooden board, that is not the job it is being asked to do.
How these blanks are made
Laser cut and hand ground in our workshop, then vacuum heat treated at Voestalpine — the mill that produced the steel. Industrial furnaces hold temperature evenly across the whole load, so every blade in a batch comes back at the hardness it was specified for. Ground through 40, 120 and 240 grit, shipped sharpened, free laser engraving included.
