Hey all you hogs, im new to convex knives with my first although being a BRKT NorhtStar, I was wondering who you all kept you knives sharp in the field. i have the Airbleeder strop from the company store and works beyond expation, but its too heavy to carry in the backcountry for bpacking trips. Any methods out there that are pretty light to carry on you back (espically since in '07 in thru-hiking the AT and want to take my growing convexes with me. Thanks for any input.
