Cold Steel President, Lynn C. Thompson has spent a lifetime collecting walking sticks and wooden weapons, and has amassed quite a collection of these beautiful handmade sticks. He has always had a particular fondness for the Knob Kerrie, a ball headed walking stick from Africa. Cold Steels interpretation of this African Walking Stick features some of the finest features of the traditional Zulu Kerrie the undulating shaft, and distinctive geodesic ball - but instead of using expensive exotic hardwoods, weve made ours out of high-impact Polypropylene. This means that, in addition to being incredibly durable, it wont rot, warp, crack, splinter, swell, shrink, mildew or fade. Although its primary function will always be as a walking stick to aid ones balance when crossing uneven, slippery or rough terrain, it also makes a formidable self-defense option in an emergency.
