The Work Sharp Whetstone Knife Sharpener is a full-size sharpening system that utilizes top-quality diamond and ceramic stones of three grits and a stable base to help you get razor-sharp edges on all your cutting tools.
i absolutely love this sharpener. you don't really need the 320 grit plate as all the sharpening happens on the other two, but very useful when needed. the pivot response takes a little time to get used to but after that its a blessing for knives with big bellied tips. remember to stop mid way during the sharpening of the tip to not damage the tip. thin blades can sometimes get caught in the plastic between the guide and the plate but it can be avoided with practice and technique. Takes very little time to get a hair shaving sharp, heck the dullest blade i have took me from cant even cut wet paper to razor sharp was an hour at the most. in all, its too easy and boring of a sharpener in the best ways possible.
