STR had a deep carry clip for a Blur I believe. It might have been for the custom titanium framed Blur he put together so the hole spacing may not match.
I have one of his Ti lowrider clips on my Ti JYD that I really like. The G&G Hawk clips are my favorite though. They look out of place on most knives, and aren't deep carry,
but they hold nice and tight to the pocket while providing that retention without chewing up your pocket since you release with a little lever. Really ingenious.
