I get the feeling we are not talking about the same knife :
This is the CRKT Sting 3B 2020... One of the nicest (and lightest) EDC I have ever used (but with a plastic sheath, not what the OP is researching). I admit the earlier Stings (I, II and III) are way heavier, much nicer and have leather sheaths.
I currently cycle the above pictured 3B with a Sting II (first edition) :
Both work very well, do what I need and never fall into my pants (and that's very important). The original is heavier and the retention of the leather sheath is just OK. I really prefer the original but most of the time I carry the CRKT POS. Go figure...
