walking stick, right handed ergonomic palm handle (Boscombe BH5)

with adjustable height but only from 72cm to 82cm. I googled "correct height for palm handle walking stick" and response is "when the top of the handle aligns level with the crease of your wrist (the prominent bone at the bottom of your wrist) while your arm hangs naturally at your side".
Please note this is a palm handle stick, which means it is shaped to fit right hand only.
