I like this sharpener, especially with the ceramic stone. Used it at work. It would be better though if you replaced the 30 degree, which most people will never use, with a 15 degree angle. imo

The 30 degree slot is there for a very god reason. The 25/20/17 angles produce a successively keener but WEAKER and faster dulling edge, as the cross sectional area gets smaller. In real-world, rougher usage, a less steep angle is not only "tougher" (less prone to rolling over or chipping) but often more useful-and stays usefully sharp for longer periods of time between resharpenings. Think of an axe blade vs a filletting knife-each serves a purpose, yet neither one is a good substitute for the other.

Maintain your knives in the field to the exact angle you set with your legendary Lansky Controlled-Angle System, or use as a fully functional, stand-alone sharpening solution. The carbide V-groove sharpens in 3 to 4 strokes. Next, freehand polish your newly sharpened edge on the built-in ceramic benchstone. Additionally, the ceramic benchstone is tapered for effectively sharpening serrations. See below for details.


1.  Carbides: 17º, 20º, 25º and 30º

qsharp_in_use_sharpen.jpgUsed to set an edge for an extremely dull blade or to sharpen the blade in seconds when the need arises. (For more information on individual angles see Which Angle Should I Use When Sharpening My Knife?)

Holding the knife with your dominant hand, and using the other hand to hold the sharpener: pull the knife through the desired angle slot. Just three or four strokes using moderate pressure will restore your blade. Rinse blade thoroughly after sharpening.

Note: Carbide is extremely aggressive and should only be used for super quick sharpening as the need arises. For general edge maintenance: use the built-in ceramic benchstone element.


2.  Ceramic Benchstone

qsharp_in_use_benchstone.jpgThe medium (800) grit ceramic element should be used in a benchstone type fashion, or like a butcher steel. The Ceramic Benchstone is harder than steel, will never wear out, and can be used often as the primary sharpening element of your QuadSharp. The Ceramic Benchstone is also tapered for sharpening serrated knives.

(PRO-TIP: Extremely dull blades should be re-profiled in one of the carbide slots before using the ceramic benchstone).

Eventually metal shavings will accumulate as dark streaks on the ceramic and will slow effectiveness. Clean with a Lansky EraserBlock.


3. Sharpening Serrations 

qsharp_in_use_serration.jpgSharpen one serration at a time by pulling the ceramic element against the grooved side of the serration. For larger serrations: use a rolling motion to sweep the corner of the sharpener from one side of the serration to the other. Repeat until serration is sharp then move to the next serration.
