I have a Bonsa switchblade or lever knife and I would like to know what time frame it was mfg. It has bone handles and the front tang is stamped Bonsa over Soligen over Germany. The back tang is stamped D B G M over Rostifrei. I would like to know if it is a common model or a hard to find collectible model. I would appreciate any info.[image][/image]
That style of knife is sometimes called a "Springer" and all Springers are quite collectible. In general Bonsa is not a brand that has much collector interest but for this knife, the pattern, (Springer) is more important than the maker. As to age, i don't know. "D.B.G.M." might be a clue. I think it is a reference to a patent. Hopefully someone who knows will post. kj
I have read that D R G M, was a mark used by German manufacturers in registering their product in all the German states. Not really a patent date but kind of like that but only applicable with in Germany. They used it on lots of products, toys, knives etc.
