I inherited an Old Timer 156 OT. It sat in a drawer for years until a few months back. I put an edge on it and man does it feel great in the hand ! It is definately a keeper. Also have an older Marbles Ideal and something called an Edge Brand #471 - Solingen Germany. Nice knives. Still need a bit of practice to get great edges on them. I'll try to get photos posted sometime soon. I don't know much about them so any info would be really appreciated.
