Lemme tell you guys how to get a good edge on a khukuri: Take one well-used EZ-Lap Model M Diamond Rod, one with the bloom well-off of it so that a beginner would say it's 'worn out'.
Watch your favorite TV show, bird feeder, sunset or whatever, while caressing the knife's edge with said diamond rod. It is advisable to hold the rod well back from the end, to avoid bloodstains on the blade. I like to tuck the butt of the knife under the left armpit like a fiddle, and roll it back and forth to get equal tickles on both sides of the blade. Ah, what music it makes!
Note: these 'strokes' should be light as a feather, and at an angle that can be easily found by laying the rod flat on the blade bevel and then raising it a 'smidgin'. The international standard for a 'smidgin' is not clearly established, but it it somewhere between a 'bit' and a 'mite'. Since this varies with the barometric pressure, time of day and phase of the moon, you will eventually produce the much-desired 'Moron' or Chanel #5 edge, which cuts like tiger shark teeth. It is a gradual process, taking several months in some cases.
Occasionally, give your knife a taste of variety with a fling on a ceramic rod, or an affair with an old, experienced (1943 vintage) oil-stone.
Finish with a few back strokes on a rough strop. Khuk's seem to have a bit of a taste for roughness. (I use an old rifle sling and red rouge. The holes for the keeper straps on the sling probably have an extra effect.)
Repeat as necessary (for me, this is about 10 minutes a day.)
