at one time, Martin Butler, Simon Lytton and Roland Robidoux all worked at the same gun shop in London, Ont. back in the early to mid '80's. Rollie is a close friend and I speak with him frequently and he is doing mostly guns now. Martin, I've lost track of. Simon as far as I'm aware is currently residing in the US.
One of the best engravers there is, Tiz Pozzobon is currently residing about 15 minutes from me on the edge of Toronto. My buddy Rollie says I shoul invest in a piece of his artistic work on one of my knives. Just not sure which knife it should to on.
