Not sure it is issued but i read somewhere it was made with their cooperation, they have been making knives for over 100 years so i guess its possible, the SBG1 model has been on my wish list for ages, one day
You could email Klotzli and ask, they were very helpful with me when i was trying to find out info on one of their knives in my collection, very approachable and friendly family run business
Incidentally, the previous manager, the father of the current management served his apprenticeship at Victorinox
