Whats this tool?

[TheEpicBlob]

Hi All,

I've been looking for a tool like this for some time, and have finally found one in the flesh (or on YouTube).
Can anyone point me in the right directions for getting my hands on one?

I call it the nutcracker vice!



I'd link the video however need 5 posts or more - You can search "3D PRINTING DIAMOND WEDDING BANDS" by Pablo Cimadevila (who incidently is a gold medal winner for the Paralympics).

Thanks,
Ben
