I sent an e-mail message directly to Fallkniven, and Peter from Fallkniven answered almost immediately:
"You’re right – for some strange reasons a few folding knives are missing the weight information. We’ll fix that later! The P weight is 72 gram or 2.54 oz"
Nice weight, in my opinion. Even more impressive is how quickly the manufacturer responded. I'm not seeing that from all knife manufacturers (won't call them out right now).
