They are machined from 5mm brass.
They have a window machined from both sides revealing the interior of the knife. The windows are inlayed with acetate the same material used for eye glass frames. There are 6 different types of inlays. Some are more transparent than others.
There is only 12 sets so if you want them, you need to get them soon.
They're made in Germany.
