When I made my cane, I used a brass ferrule and stuck in a rubber cork.

What I like about a rubber cork is, if I choose the size wisely, that I
can replace it with wine corks, which I have in abundance.

Lee Valley part # 45K42.18 has been quite robust for me; over four
years of rough trails and concrete sidewalks and the rubber tip is
still ok.
