I have yet to find an entirely satisfactory solution for sharpening knives in the outdoors.

When sharpening knives at home, I use my (now very old) Spyderco Sharpmaker, and I’ve been pleased with it. But it’s too big and bulky to bring on a hike or a camping trip, or to put in a kit for an emergency. The “v” shaped sharpeners I’ve seen (such as https://www.amazon.com/Smiths-CCKS-2-Step-Knife-Sharpener/dp/B00032S02K/) have bad reputations and I’d be pretty desperate to try one.

The Fallkniven DC4 is not crazy expensive for a pocket sharpening stone, and I’ve put mine to good use. Something smaller and lighter would be better for what I envision — I think the last time I used mine was for a neighbor’s axe, and it was but a minute to walk home, get it, and bring it back.

My use case is that I’m carrying everything I’ve got, and I’ve done Something Regrettable to my knife that I feel compelled to fix, with what I have with me.

I’m eyeballing a Victornox pen-shaped sharpener (https://www.amazon.com/Victorinox-4-3323-X1-Sharpener-Portable-Sharpening/dp/B000AR7AKG/) and it looks like it wouldn’t be had. I’d love something better at around this approximate size, if such a thing exists.

Any ideas?
