I recently bought two of these, both new and very nice knives. They were from two different dealers stating they were 20+ years old. Any info on this model? I can't post pictures here, but they are the wood handle, brass bolsters with the "press" liner lock release to close the knife....Were these USA made ( as they are marked)? Thanks for any info....I am a long time collector but new to this model and the only other Kabars I had before this was a few 1179s....
