Have communicated with the seller, the box is Japanese domestic issue and the knife is early production.
senate- the early G10 knives had the conventional blade, it changed to flat ground when the liner was included in the later knives.
this purchase ended my coolecting year on a high, a black CO7S, a linerless G10 and an old LH S/Steel CO7s with POLICE MODEL on the blade. Is there no end to the variations?
Sorry can't post any images at this time, are there instructions somewhere as to how I should go about it?
