How a knife geometry chooses a job
Edge angle, thickness, and grind decide whether a knife slices, chops, or survives a hard blow.

From the opening
A knife's geometry chooses its job because the angle of the edge, the thickness behind it, and the shape of the grind decide how easily the wedge enters and how much steel is left to support it. The same steel in two shapes is two different tools. The opening covers angle sets how easily it enters, thickness behind the edge supports it, and grind shape changes the drag.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
