A friend of mine showed me this lock and I thought I would see if anyone here has heard of it.
It's a brand called HYT and I believe it is a Chinese or Japanese brand. Apparently it is very rare and discontinued.
The keyway is curved so it is pretty much impossible to pick or bump. Also the key is basically a chain. In order to open the lock the key has to be "injected" into the keyway.
Here is a video link and a few pictures.
