Enter knife style, hardness, edge goal, and blade width to estimate a sharpening angle and spine height.
Tap an example to prefill the calculator with sample values.
Hard gyuto
Japanese chef knife with harder steel
Harder, thinner kitchen steels can support a lower angle when the goal is clean slicing rather than abuse tolerance.
Result: Harder steel supports a keener edge, though your actual sharpening system still controls the final effective angle.
EDC pocket knife
Balanced daily-use folder with more durability
Pocket knives usually land in the middle: enough bite to cut well, but sturdy enough to avoid chipping during daily carry use.
Result: A slightly steeper angle trades some slicing aggression for better edge stability.
Camp knife
Tough-use outdoor edge
Outdoor and hard-use knives usually benefit from a more durable angle and often a small micro-bevel on top of it.
Result: Tough-use knives often want a sturdier edge that resists rolling or chipping under rougher work.
