He had Yucca fiber sandals"
I have found that yucca fiber is a great material, it is easy to refine, and very strong. one time I was teaching a troop of boy scouts how to light fires with flint and steel using some yucca fiber refined by yours truly (worked great roughly on par with jute or sisal)
Although I am still fairly young I often carry a small knife in my watch pocket my favorite's being a Case peanut(chestnut bone with an interesting checkered pattern), A 108OT(not original schrade they closed before my knife purchasing days), or an opinel #5(until I lost it going for a run)
I may add some pictures after I figure out how to load them onto this device & post them here
