I am the world's worst at sharpening a knife. The sharpmaker helped solve that problem. Used it on a trout fishing trip to Taneycomo to keep everyone's fillet knife and my Dumpster Mutt DC sharp right after I got it. It kept my DMDC sharp enough to clean trout with. The people I went with all have one now. The sharpmaker mainly gets used at the kitchen table now. I use this in the field: http://www.worksharptools.com/knife/sharpeners/other-sharpeners/guided-field-sharpener-221.html
