Guys, one of the sharpeners I use a lot for touch up of smaller blades (not the khukuris) is the Spyderco Tri-Angle Sharpmaker.  The unit is as simple as can be – the brass rods are to protect your hand and then it comes with two pairs of stones – fine and medium basically.  You put the stones in the angle of your choice and the hold your knife straight vertically as you run the blade down the stone.  The unit works really well for maintaining pocket knives and blades that are ballpark 5-8″ – much longer and it just really gets tedious.

Now I don’t use the medium grit brown colored traingles much.  I use the fine and the optional Ultra-Fine triangles for most of my maintenance.  The Ultra-Fine stones (ceramic really) can put a hair popping razor edge on blades.  One thing to bear in mind if you you want the ultra fine stones is that Spyderco sells them by the stone – why?  I have no idea and think it is confusing – you really need two.

I keep this on my desk (at home 🙂 and do touch ups when I am on the phone, need to take a break, etc. and pretty much use it every day:

Here are the Ultra-Fine stones – remember that you need to buy two:
