These knives of mine I've had and used for 40 years except for the light coloured handled knife which I've only had for 30 years. There is 1 x Barnsley, 1 x T Dixon& Sons, 1 x J. Dixon, 1 x J. Dixon & Sons and 4 Osborne knives with different stamps. These all hold razor edges, especially 1 of the Dixon and the Barnsley, and are easy to sharpen. These knives are basically the same shape as when I first got them and are used practically every day and hold there edge. I'm sure these aren't any modern space age steel with fancy names and numbers and a couple of them probably go back to the beginning of the 20th. century but they are a pleasure to use.
