The angle a knife is sharpened to is one of the most consequential decisions in the sharpening process. Most people never think about it. Most sharpening services don't either.

What the angle means

Edge angle is measured per side. A 20° edge has 20 degrees of bevel on each side, creating a 40° included angle at the apex. A lower angle is thinner and sharper. A higher angle is thicker and more durable.

There is no universally correct angle. The right angle depends on three things: the steel, the knife's intended use, and how the knife will be maintained.

The common profiles

12° to 15° per side is the territory of fine Japanese kitchen knives and premium slicing blades. At this angle the edge is extremely keen and moves through food with minimal resistance. It is also more fragile. Hard contact with bone, frozen food, or a glass cutting board can chip or roll the edge. Knives at this angle reward careful use and proper maintenance.

17° to 20° per side is the working range for most Western chef knives and everyday kitchen blades. Sharp enough for precise work, durable enough for general cooking. Wüsthof, Victorinox, and most European kitchen knives leave the factory in this range. It is the most versatile sharpening angle for a busy home kitchen.

22° to 25° per side is appropriate for heavy-duty utility, outdoor, and pocket knives that contact hard surfaces or do rough work. The edge sacrifices some keenness for resilience. A hunting knife, a camp knife, or a machete belongs in this range.

Why this matters for your knives

A sharpener who applies the same angle to every knife regardless of steel or purpose is not serving the knife. A Japanese gyuto sharpened at 25° has been given a geometry it was never designed for. A soft stainless utility knife sharpened at 12° will roll immediately under normal use.

At Stronghold Guild, every knife is evaluated for its steel type, existing geometry, and intended use before an angle is selected. The goal is to restore the knife to its correct geometry, not to impose a convenient standard on every blade that comes through.
