Knife sharpening is a powerfully divisive topic, similar to asking a car guy whether they prefer manuals or automatics. You see, there are three basic types of sharpeners – guided angle sharpeners (like this one), freehand sharpeners (like Japanese water stones - these are also good but unless you're a Japanese samurai you'll probably do it wrong) and pull through sharpeners (like your uncle John uses on his kitchen knives but all they do is remove tons of metal and create a toothy burr.) Guided angle sharpeners are essentially glorified jigs, a device that you mount the knife in and can then apply an accurate angle on a stone to the edge bevel of the blade to create a consistent edge. By switching between the different grit stones, you end up with a perfectly sharpened edge. Every time. This set comes with everything you need, including all the different sharpening stones. And if you need any replacement stones, just check out our other listings for those too.
Two options available: Counter mounted (using included C-clamp), or free standing. See images for dimensions and specs to help you figure out what will work for you.
