17° Angle - A severe angle recommended for razor blades, fillet knives or similar tools. An extremely sharp but delicate edge.

20° Angle - A commonly used angle for higher quality blades and provides an excellent edge for kitchen cutlery and slicing knives.

25° Angle - The recommended angle for most knives that need a durable, sharp edge. Ideal for hunting and outdoor knives.

30° Angle - An outstanding angle for knives that cut cardboard, rope or carpets. Best for heavy duty use.
