A clip and coping combo is somewhat rare. If you want to expand your search to clip and sheepsfoot(like the 2 blade ‘18 forum knife) you have quite a few more options.
If you go back a page or two you’ll find a thread that covers a similar topic, but off the top of my head you have
S&M horticulturist knife
Schrade 93OT
Böker stockman jack
There’s a Buck option that I don’t recall the exact name
If you can settle for a spear main then you have even more options. Two blade knives with a straight edge secondary are not the most common blade selection, but it looks like people are finally seeing the utility in it. There have been quite a few recent production knives offered that fit this bill, and that’s a great thing.
