OK, now this Im into. I just put in some offers on some of these models on ebay but was wondering what does it mean when the seller says how many dots the knife was made with? Ive seen ten dots, 7 dots, 3 dots, etc... and dont know what the heck their talking about. Ive mostly been placing offers on these three models from the 1960's/1970's on knives that look borderline new.
May I make a recommendation (though it may not be popular with you at the moment)?
Hold off making bids on vintage knives on the auction sites until you educate yourself some about the knives, the patterns, what the dots mean and the value of the knives you are looking at. Right now you are like a babe in the woods. (And I don't mean that condescendingly, there's a lot to learn and it's a process. Sometimes a long one.)
Best case scenario is that you'll end up with an authentic knife in good condition (as described). There are lots of worst case scenarios for the uninformed.
It pays to do your homework and not be in a big rush. YMMV and it's just my advice. Feel free to discount it but please understand the consequences.
Thats great and very wise advice from Elliott. It will take a long time to learn the variations of variations

. Case knives have had many different tang markings over the years. The 60's era knives you mentioned bidding on will not have a dot system, and there are two variations just for the 60's era knives. Then we also have the Tested era....
The newer stuff I would have to look up because I don't follow the new stuff.
Some of the like new knives that get listed on the auction site, look like new because they have been polished up to look that way. Its very easy though for someone thats not very good with a buffer, to take what would have been a knife that just showed its age, (which is a good thing around here

) but was still in great condition, and lower the value and desirability of that knife.
It will still make a great user though, if you don't pay a premium price for it.
The amount of knowledge that folks have here to tap into is big. Don't be afraid to ask questions, folks will be more than happy to answer them for you.
I think we all shared your enthusiasm when we first got started, and still do.
But as Elliott mentioned, there is a lot to learn , and it will require a lot of your time and effort. Its an investment though, because the more you know, the less apt you are to get a bad deal on a knife. Plus, the learning part is really fun . And the learning never stops.
