Mark Evans carves images onto leather with knives. He's deliciously unpretentious about his craft:
Art doesn't get more primal than etching animal skins with a big knife. I don't do 'pseudo intellectual' I make art.
And that's it: no postmodern angst, no childhood issues. Just a guy with a knife and a sheet of leather. At the link, you'll find a gallery of his amazingly-detailed work.
