My fillet and hunting knives were getting really dull and I am the worst at sharpening any knife. I went to Cabelas and bought a Work Sharp($99.99 version) sharpening kit. I watched the furnished video and after changing the belt once was able to sharpen every knife in the house (including 8 kitchen, 3 hunting and 4 fillet knives) in about 20 minutes. Really easy to use. The templet I chose was the 50 degree one there are two other templates and 6 belts with the unit. The belt I chose appears to be able to sharpen many more.
