The Lansky Controlled-Angle Sharpening System allows users 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 sharpening 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 Extra-Coarse to Ultra-Fine hones provide an excellent range of grits for complete edge care and maintenance. The USA made Lansky system is perfect for outdoor sporting knives, kitchen knives or workshop knives, and offers the widest range of accessories available. In production for over 35 years, the Lansky Sharpening System has been the most preferred, and best sharpening system for knife enthusiasts worldwide.
