In the UK Hazel is traditional.
I'm not a fan of Cold Steel, because of their marketing tactics and ways of doing business, but they do make some good products. As a suggestion, have you thought about something like this?http://www.coldsteel.com/Product/91PBS/IRISH_BLACKTHORN_WALKING_STICK.aspx
Don’t you have any ‘sticks’ growing near to where you are Mad one ?
Like some of the others I use dried river cane/bamboo. It is light and durable. My piece has a paracord handle and rubber feet on both ends. I cut it so I could stash small items in the top section if I wanted. I also put a large washer in the bottom foot to help protect it.I like your idea of the fiberglass shovel/hoe handle. I would think the diameter might be a little much. Instead, what about a replacement golf club shaft?
