Does it have a manufacturers name stamped on it anywhere?
I have Robert Sorby, Marples (Rocket lolly and also wood handled), T Althamson of Penrith, Stormont, Ibbotson ,Henry Taylor and a german manufacturer with a raging bull logo that I can't remember right now.
My local secondhand toolseller often has them in and at a quid a pop I can't resist, plus a very generous customer of mine kindly gave me a good selection of her now dead fathers Marples chisels (amongst various other tools) which I sharpened on a mates Tormek and am now trying to do justice to by using whenever I get the chance.
