We got one from our local agricultral shop( sells everything from tractors to fence posts) so it you have anything like that near you try there. Although ours is metal and weighs a ton so I never use is lol
Some ntack shops have them, but usually at twice the price of Agri shop. Try to get a wooden handled one, they are lovely. Sadly I bent mine in a stupid moment and now have a heavy metal handled one.
