Usually I don't have any hiking poles with me when walking. From time to time I think it would be great to wander one or two kilometers with some support while on the track. I then often end up with a crooked, harsh and heavy stick I found in the forest nearby. These pieces don't really satisfy my needs and thus get thrown away soon after.
What characteristics should I look for in sticks in the forest to be used as a hiking sticks and where to look for them (which bush, tree etc.)?
