Best portable sharpener?

[Stirling3749]

I'm on the hunt for a product for touching up my knives while out in the bush,figured you guys might have some suggestions.
Would be nice if it could also do little multitool scissors and serrated edges as well as broader edges like axes/shovels.

I have a spyderco doublestuff and a 5" diamond stone for mine, plus a small strop and sandpaper if I have a convex edge knife.

DMT Duofold's are great, as are Falkniven's DC4 model's

I like the Spyderco Doublestuff and Fallkniven stones. I often use the side of a leather boot heel to strop.

I have a Double Stuff , Spyderco Profiles ( fave. ) , several DMT Duofolds . I have also got a baggie of strops , and very fine wet or dry glued to a bit of scrap mousepad .

The last solution is great , as it's virtually a freebie .

Hey I like those little Spyderco double siders, That might just be what I'm after.
A boot heel eh? have to say I havn't heard that one before but I have gotten descent results with the underside of a coffee mug. 
Thanks everyone.

Another vote for the Fallkniven DC4, great sharpener IMO.

I'm not a sharpening guru, but I use an  DMT dia-sharp diamond cards (green,blue.red)  and a Meyerco Sharpen - It .

I've got a gatco triceps after a little practice it works pretty good
