I know this is an old one, but...
@Squelchtone let me borrow his TrioVing at the last TOOOL meetup in Boston after I spent 2.5 hours trying to get it open. The guy is a total mensch. He's never met me before and lets me walk out of the place with an amazing lock and some street sweeper bristles. Amazingly generous!
Anyway....

BOOOOOOOOOOOOOOOOOMMMMMMM!!!!!!!!
Got it open!
Here's what I did:
I used the Sparrows Dog Ear Squared .032" flat bar and loaded it up with tension. I went down the stack two or three times with a Sparrows Offset Hybrid, clicking everything in place. I got a false set, but there were only a couple that needed to be set after that. The biggest mistake I made was trying to pick this thing like it was a standard spooled lock, like an ABUS 83. I was using light tension, feeling for the counter rotation, clicking it in place, hearing pins drop, resetting them, rinse and repeat. Being aggressive with this lock was the key (at least for me).
Thanks again to @Squelchtone! I'm going to find a way to cut a "key" for this. Seeing as how no one can find a blank, I might just take a .040" piece of metal, bent it at the top to match the right hook at the top of the keyway, and file it down to match the key pins. If it works, I'll post what I did with pics, vids, etc...
Thanks again @Squelchtone - you made my day,
