Cold Steel African Walking Stick features some of the best parts of traditional Zulu Kerries like an undulating shaft, and the traditional geodesic ball grip. However, instead of using a costly exotic hardwood, we've made ours out of black Polypropylene. This means that, in addition to being unbreakable, it's also impervious to the elements. It will never rot, warp, crack, splinter, swell, shrink, mildew or fade, and it's ready for all the wear and tear you, and the world, can dish out. It also makes a formidable tool for self-defense in an emergency.
