Zero Tolerance, Jens Ansø, UK legal carry, Wharncliffe blade shape, Magnacut stainless steel...what's not to like! The Zero Tolerance Anso Slipjoint is such a classy little folder. The blade is a stylish wharncliffe design with a stonewash finish and a nail nick to open meaning it can be carried pretty much anywhere. The handle is simply two slabs of the toughest G10 with a blue anodised aluminium spacer which lends a real quality aesthetic to an already stunning knife.
