All About Pocket Knives

As I've posted elsewhere, I'm a Newbie and I have been thrust into the World of Pocket Knives after acquiring a collection of mostly Case Knives. There were other knives as well including the one in the pictures attached. Does anyone have any idea who may have made this knife? The white is real Ivory and of course the Turquoise is real as well. The family of the PO told me he bought this knife at Sturgis Bike Week years ago. There is another one I have yet to clean up as well as another one made by someone else. Apparently he bought them different years and 2 of them from the same maker. I'm inclined to believe this was made by someone unknown who went to large events and sold his handmade knives. They seemed to be the "Show pieces" of the collection. They seem to be pretty well made knives. I know at first glance they look like those cheap "Handmade" knives you currently see online that come from Pakistan or wherever but I don't think they are because they're at least 20 years old or older... and the Ivory and Turquoise are real.
Thanks in advance!

Don’t know anything about your knife, but dang! it’s a pretty one.

At first glance, it reminded me of a Yellowhorse knife (David Yellowhorse). It's not, no markings, but then I've seen his knives without markings. I'm no expert on Yellowhorse knives. But he does use a lot turquoise.

You need a Yellowhorse expert to chime in.

Either way, it appears from the pics to be high quality.

You might try searching Arizona Custom knives and look for makers whose last name begins with B and then try P, I think those are the initials on the blade? That would be the best place to search since they have so many custom knives and you can search by maker.
It’s a gorgeous knife, what a show piece.

I just checked Arizona Custom Knives and no luck. Could be Yellowhorse I suppose but both of the knives have the "P B" on them. Doesn't seem likely they would be by Yellowhorse unless they were personalized. The third knife has a different maker's mark and it's folded steel with Scrimshaw on the scales. I'll add pics of those tonight or tomorrow.
Thank you for the insights so far!

Wow, your knife covers a gauntlet of possibilities as to who made it, O-shot.
Pakistan and India did come to mind upon first glance, but after closer scrutiny I have my doubts about that.
I'm leaning toward Yellowhorse due to the color combination and blade grind, but without original info who knows.
It certainly is an attractive knife, and one I would buy for myself, can't wait to see the others.
Welcome to the forum!

Here are pics of the other knife by this maker. This knife is much lighter in weight because it doesn't have the Brass Bolsters the other one has.
The third knife (by a different maker) is undergoing some repair work so when I post pics of that one the bolsters on one side will be missing. They were rusty so I polished the rust off and now I need to acid etch them to bring the grain back out.

Phil Booth hand made custom?

I see many similar knives everyday at www.arizonacustomknives.com , and a few are made by Santa Fe Stoneworks as well as David Yellowstone.
I don't know if Santa Fe is associated with Yellowstone or not, but their work looks very much the same.
This 2nd knife is also quite a looker, O-shot, nice!
I'm liking who Eric suggested above, Phil Booth custom.

The blade design and finish on that first knife looks like a custom to me, rather than an import. I am guessing that it is a fairly well-made and expensive Custom knife, but of course there is no way to know for sure unless someone can identify it.
