god I have more things to sharpen knives than I do firearms in my house.. If I am making a knife or if one is super neglected, I have a series of diamond stones ranging from xtra course to medium that I use to get any grinding/filing marks/dents out and set my primary edge. Then I start with wet stones and and work up to my extra fine stone which is in like the 5k grit area I think. I put my stones away and go to the high speed buffing wheel fine buffing compound and start buffing untill its back to mirror smooth. After thats done I get my extra fine stone out and put the secondary edge on which is normally at 15degrees then a quick pass at the buffing wheel. I dont normally use any sort of jig, I think its muscle memory now. If the knife is super special to me I have some Japanese water stones I can add to the mix. Granted this process takes about an hour when its done you have one heck of an edge. If I got a knife that just needs a little attention the extra fine stone comes out and 5 min later done. For my kitchen knife I will usually go to a sodium rod or a leather strap.
