They don't actually exist yet, so no. Edit - oops, they do thanks @Useris that the general view about the litelok.... not recommended then?
A lighter, strong lock is possible I'm sure, but I need to convinced.
I watched a video of someone picking the fahgettaboudit, and I think it's faked. It appears to be picking the lock, not breaking it, yet after you can remove and replace the shackle without the key meaning the lock is broken, so it probably was before they started filming.
.
Being able to lock without the key is a bug not a feature : you don't want to realise you haven't brought the key after it's already locked.
Wearing this lock would be foolish in case you end up in A&E without the key. Have a look at at hiplok if you want to wear a lock.
