As an update, I bought one of the Cold Steel blackthorn and the African walking stick canes. The cheapest price turned out to be ordering via Walmart online, since the total came to over $ 50, and that got me free shipping. Shipping canes turns out to be surprisingly expensive. I discovered that both of them take a 1" cane or crutch tip, and that makes a big difference in reducing the sliding of the hard polypropylene against the sidewalk. I am using a piece of paracord as a wrist strap. The knob-like grips work well for my large hands.
