Angle constancy is the most critical and the most elusive element of hand sharpening. The Lansky Controlled-Angle System is a guided knife sharpening system that ensures that your knife edge sharpens to the exact bevel you specify.

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 Lansky system is perfect for outdoor sporting, kitchen or workshop knives, and offers the widest range of accessories available. In production for over 40 years, the Lansky Sharpening System has been the most preferred, and best sharpening system for DIY and cutlery enthusiasts worldwide.

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
