Belt sander followed by a pasted leather belt with some compound is what I use for my knives. Easy and very fast. I use a harbor freight 1x30 ($50 +/-) leather belt for the same is $25 or so with the compound. 220 grit followed by the leather belt with compound for deburring will give you a very serviceable knife edge. You can go much higher if you like. But done right will shave arm hair easily. An edge guide can be bought or made. I bought mine but don't use it any more.
