A 4' rattan stick is a good hiking choice. You can leave it that length, or trim to your preferred cane length (39", for me).

How wide does it have to be to have sufficient strength for a fighting stick??
Pretty close to finishing this piece of hickory, which is more of a club than a walking stick. It's 1 1/2" wide at the bottom, 1" at top. Length is 43". Making it for my former-Marine brother (who has corrected me with "once a Marine, always a Marine").
