Don't know how many times I posted this over the years, here. For around $30.00 you can order a small 1"x30"grinder from Nothern Freight or Michigan Tools, or find them locally. That, a couple of 600 grit belts, unless you're going to do an edge from scratch, in which case throw in a 220 grit and a 400. Plus, to save a bit of time, one of those 1 X 30 leather honing belts. You can get all those at TKS or Jantz or Sheffied,or...list goes on. With a little practice on some old kitchen knives you can put a hair popping edge on a knife in about 1 minute flat. That, or those cardboard sharpening wheels that Curdog mentions, if you have a buffer or wheel grinder. On the belt grinder, you do the sharpening on the area of the belt between the top of the platen and the top wheel.........gives you a super sharp convex edge. The belts are cheap, and last a long time if you only use them for sharpening. Actually the 1 x 30 belts are one of the few sized I can find locally. Even Sears has them. In the long run, you save a lot of time and money, and the learning curve is a lot faster than learning to use a stone; not that you shouldn't learn how to "touch up"a blade with a stone for when out in the field. But, for home use I'll take a the belt grinder any day of the week.
