What stone?

What stone would y'all recommend for keeping in the front pouch of my Green Beret sheath?
Thanks!

Not sure of what size would fit but maybe a Spyderco Double Stuff or check out https://www.baryonyxknife.com/sharpeners.html , he's got some nice small dual grit stones that would be great. The arctic fox might work?
