These sharpening threads have reminded me that Rockler has a 5-inch burnisher w/ hardwood handle for about $25 USD. It's original purpose is to put a burr on steel cabinet scrapers, but it would work admirably for burnishing a khukuri edge as well. A very poor picture of it can be seen at:

They also have waterstones, hones, chrome oxide compound, and lotsa other nifty stuff.
