Does the job...
Whatever your thoughts on pull-through sharpeners, having something in your pack to deal with a dull blade is advisable and this offers a great way to do just that when out in the wild. IMO ceramic is preferable over carbide or diamond... unless your blade is proper knackered, the others are just too aggressive. This is a good bit of kit, does what it is supposed to and put a usable edge on one of my cheap folders in less than 2 min. The benchstone is a nice touch too, good for touching up serrated edges. 5*
