These knives are from the 108mm Victorinox knives. The 108mm range started when Victorinox began making the German Army Knife (GAK) to specification for the German army.
Based on the GAK, a couple of other knives have been available until recently. There are a limited number of different tools in the series and the 108mm knives are at most 3 layers thick. The knives are very durable and functional.
I will take more pictures of the individual knives later ;)
Update: check them out :)
