This is a gorgeous Rob Bayley survival knife, about nine years old, as confirmed by Rob recently, and in excellent condition. Rob didn't authenticate anything at that time, hence there is no leather 'certificate of authenticity'. It is a one-off 'Evolution' model, a forerunner to Rob's chunky S5's. It is in 5.2mm RWL34 with secondary hardened H/T. There were only four S-type Evolutions: two 5", one 6" (this one) and one just over 7". So this is truly unique. Price is £700 net to me or USD/EUR equivalent. Open to sensible offers. I'm in the UK.
