Something called "ultimate hunter". The name is a bit macho for my taste but it promised to be a folding knife that locked out as strongly as a fixed knife, and it is. (I didn't put that very well but you know what I mean). very robust. Takes an excellent edge too. Very pleased with it. Only been using it six months or so but so far its looking very good.

Previously used an Opinel, which are also nice knives, though obviously a lot lighter. That's been demoted to a gardening knife now.
