Jason Klass is a mighty ambitious outdoors fanatic and DIYster. My favorite? These DIY trekking poles made from carbon golf club shafts. "Overall, I ended up with a sturdy, finished product that only weighed 4.4 oz. per pole. The cost per pole was about $18.50 since I already had the glue, etc. that I needed. While not as light as some of the commercially available ones, like Gossamer Gear Light Trek 4s, it proved to be pretty cost effective with a little time investment. I think the most difficult part was tracking down the components. You could make a pair for $37 (maybe less) if you want to lose weight and don't mind the homemade look."
