Colley & Co. (with an S above a symbol), Sheffield blade. I reground this even though it had been reground by someone else before. I needed to clean up some stuff. Scales are G10. Some of the pics give weird reflections or marks and all, I don't know why. Notice how the pivot and wedge pins match the rest of the scale design and go straight through. I think it's pretty cool. This will NOT be sold (for now) lol.
