Sharpening and Care

Hammer Stahl Sharpening System

A 20-degree factory edge is only worth having if you can put it back. Three tools do that: a guided stone system, a sharpening steel, and a guard to keep the edge you just made.

Honing and Sharpening Are Not the Same Job

Most knives that feel blunt are not blunt. The edge has simply rolled over sideways from thousands of small contacts with the board, and what it needs is straightening, not grinding. That is what a sharpening steel does: run the blade along it at 20 degrees a few times before a session and the edge stands back up, with no metal removed at all. Done every few uses, it is the single habit that keeps hammer stahl knives feeling new.

Sharpening is the other job, and it is only needed when honing stops working – typically once or twice a year in a home kitchen. Then you are removing steel to cut a fresh bevel, which is what the three-piece system with its 1000 and 6000 grit stones and its bamboo holder is for. The holder matters more than it looks: it fixes the angle so the bevel you cut is the bevel the factory cut.

The third tool is the least glamorous and the most quietly useful. A blade guard stops a finished edge from resting against other steel in a drawer, which is where most newly sharpened knives lose their edge again within a week.

Sharpening Hammer Stahl Knives: Questions

What angle should I sharpen a Hammer Stahl knife to?

Twenty degrees per side. That is the bevel every blade in the range leaves the factory with, laser-honed onto a taper-ground blade, and holding the same angle is what keeps the edge behaving the way it was designed to. It is also a completely standard angle, so any guided system, stone or pull-through you already own will return the knife to spec.

How often should I use the sharpening steel?

Every few uses, and always before a long prep session rather than after it. Honing takes about fifteen seconds and removes no metal – it straightens an edge that has rolled – so there is no cost to doing it often. A knife honed regularly needs real sharpening perhaps once or twice a year instead of every couple of months.

What are the 1000 and 6000 grit stones for?

The 1000 grit does the cutting: it removes steel and re-establishes the bevel on an edge that honing can no longer save. The 6000 grit polishes what the coarse stone left behind, refining the scratch pattern into a smooth, keen finish. Start coarse, finish fine, and keep the blade at 20 degrees on both – the bamboo holder in the three-piece system is there to make that repeatable.

Do I need a blade guard?

If your knives live in a drawer, yes. A freshly sharpened edge is a very thin piece of steel, and knocking it against other cutlery is the fastest way to undo the work you just did. A guard also makes a knife safe to reach for blind. If everything is stored in a block or on a magnetic strip, the edges never touch metal and a guard is optional.
