A friend was supposed to send me one of the pocket diamond hones, but that hasn't happened yet. I've got a Arkansas stone en route.
At home, I use a Sharpmaker, of course. It can even be used on unconventional shapes like my kukuris.
I just got the Native, so I don't know how often I'll have to sharpen, but based on the typically light (and may it ever be!) tasking, I probably won't have to sharpen more than about once every three weeks or month.
