I inherited a good size knife collection and wanted to know if any of them were really collectibles. Two knives that caught my attention were a Boker Applegate OSS 1942 number 549 and a Kershaw Trooper serial 31,486 made in 2003. All of the knives are still in their original boxes and were never used by my Father. It seems like he took really good care of them and kind of want to find out more about them.
