I know that ... I just wanted to know whether in the intervening 10+ years since the pen trick whether anyone has violated a master lock force 5, 6, or street cuff. Given that there still is no evidence but just speculation and truisms about how every lock is vulnerable in some way, I'll sleep soundly using my lock. Yes, it can be cut, but probably only with power tools, and at that point, I'll just fall back on it's 2500 dollar insurance. Also I'm not expecting anyone to be carrying around power tools in broad day on a busy university campus.

Also, I think it bears mentioning that not all tubular locks are vulnerable, according to some online sources. Perhaps mine is one.I hope I never have to find out.

The only video I've found of a Master lock tubular lock being compromised is this:

Which makes me wonder: if he could have unlocked it with a Bic pen, why didn't he just do that instead of screwing around with the real tools? And even as he said, the Cuff isn't like an usual tubular lock and requires a lot of tension to pick.

In any case if anyone is interested in getting the Force 6 just be aware that the space inside the shackle is very narrow ... i have trouble squeezing my 23c wheels and frame inside the shackle with a thin bike lockpost. My frame tubes are THIN too ... they're teardrop shaped and not much thicker than the wheels (not like the massive rounded square tubes you see nowadays).

Lock envy. I want a Cuff now!
