Wow, what a question!
I am not even sure how to answer that one. We have made, at last count, over 10 million of them buggers so far and just about every variation you can think of has been done at one time or another. We did a bunch with Yellowhorse handles, quite a few projects for Harley Davidson, too many to count special projects for other individuals and companies like Bass Pro, Cabelas, Gander Mountain. You can find them with gold engraving on the blade, laser etching in the handle, laser cut outs on the blade. Stag, elk, colored laminates, bone, ivory, are some of the handle types. Damascus, BG-42, ATS-34, S30V, 440hc, 425mod, 420HC are some of the steel types used.
If you are looking for all the variations of the standard version, there are quite a few of those as well. You mentioned 4 dot, we did 2, 3 and 4 dot and those were just special stampings used to mark major changes in the production process.
And this does not even touch the many knives made back when we had our custom shop during the 80's and early 90's, or the knives made in the current Custom shop via the internet.
I have never heard of anyone claiming to have all or even most of the 110 variations but boy would that make for an impressive display!!
I hope this helps,
