OP, the photo is from CPK's IG page which was also posted in here in these past couple of days. The person who is holding those two CPKs is probably Mark Scrimgeour AKA CPK-Mark. The CPK on the far side of the frame looks to be one of the special bowie variant SDFKs. The one on the nearside which has caught your eyes, that DEK2, I reckon is one of his special hollow grind ones which may only be available in a very limited quantity (a few only). That one pictured is either possibly spoken for already or being taken to Blade 2023.
