Information needed on Puma Buddy 8363 and Early 70's Rigid Sidewinder

[bonesamon1]

I have a Puma Buddy 6383 made in Q3 of 1967 that is in real nice condition, although there are some marks (either light cutting or light sharpening) on the blade, but it does not show very much on the knife. It actually looks much worse in these photos. My main question is when did they start to make the Puma Buddy exactly, if anyone knows? Also, any other neat tid bits of info about the knife would be greatly appreciated. Next is a absolutely new condition Rigid. I have been told, and through my research, have come up with it being a Sidewinder. The knife itself is pristine, the blade has never cut anything, and the handle is perfect. The sheath is about a 8 out of 10. There is a 3/16-14 cut along the back side of that I put in there when I was a about 8 or 9 years old, and not permitted to touch the my fathers knives, and I put it in the sheath the wrong way. When it would not go, I panicked and forced it, and slit the sheath. Needless to say, i got justly pumished for my mistake,and for the lie of saying " I did not do it" lol. Again, any information on these old Rigid knives would be aprecciated. I once heard that these early Rigid knives were some Buck Knife employees, experimenting with some designs that they wanted to try and promote on their own. Whether true or not I don't know. Whatever you have I would like to know. I attatched a couple pics, if anyone wants more just let me know. My email is bones0831@aol.com. Thanks.
