Hi mates!
Here is a tip for German speaking members. The German "messermagazin" has a special issue once to twice a year, called "Gear". This is the only German EDC and Geqr magazine I know of (in fact iI do nit even know any in English, are there any?)
In the now new issue, there is a nuce article on the history of MT, with some nice shots of vintage and some modern MT, covering the LM-style tools, older multipliers and even one piece tools. Interresting read, even if there is way more informazion here on the forums.
