This product allows the user to select the sharpening angles that are best suited for their knife's intended use. The four sharpening angles and their uses are listed below:

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.

Usage:

The knife clamp included in the system holds the knife steady, and holds the angle guide static and firm, so that the user can achieve the desired angle with every stroke of the sharpener. The Coarse to Fine hones provide a great range of grits for complete edge care and maintenance. The Serrated sharpening hone also allows sharpening of serrated knives with this system. The product is perfect for outdoor sporting, kitchen or workshop knives, and offers the widest range of accessories available.
