pocket straight razor?

[Jmora]

I often find myself in need of a razor blade, like when I miss a bit shaving in the morning. Would it be possible to reprofile a blade on a pocket knife so that it has a burr that could be used like a straight razor? or is this just impossible for reasons of steel type, blade geometry etc. I imagine having a two bladed knife, one with an EDC blade, and another smaller reprofiled straight razor edge for emergencies. I mean this is something only a knife nerd would even think of, it would be more practical to just carry a disposable razor or something in my bag, but I'm interested in the possibilities.

There are videos showing people shave with a sharpened Axe, so anything is possible.

I think you would need a blade with quite hard steel to hold an edge but its doable
Or you could carry one of these

I just use my pocket knife, not close shave like razor but good enough in a pinch. I always keep the small blade on my SAK profiled to very acute angle and very very sharp.

Not sure how reliable they are or where to find them but I've seen "Case"-type knives with straight razor blades.

Bear and Sons makes some folding razors, as does Sarge.

some pretty cool products, I think I like jzmtl's pocket knife idea the best, I just need a bit more time to get the hang of this reprofiling thing and I might try out something like that.
