this one has pretty significant collectors value I believe slightly less so being combination edge rather than Plainedge, it is probably again ATS 55, a good knife with nice ergonomics. if they happen to have the baby version of this knife. this is a real treasure and I would definitely pick up one of those I had one that I lost. a long time ago and in combination edge or fully serrated. I would say it is one of the best keychain knives ever made by production company. I would definitely picked up the one you got for $65.
