I have an APEX sharpener that will put a razor edge on any blade but it requires a bit of work (google APEX out of Mt. Hood, OR) so I've taken to sharpening my EDC blades (work blade) with the back side of a 1x30" sanding belt and a Harborfreight $40.00 sander. I just lay down some red ruge on the belt and then work the blade on it a few passes and it's razor sharp again. It will pop hairs after 4-5 passes on each side. Just let the belt do the work.
