...Regarding the Danish edition of the Wave, I took a quick look at Leathermans site and couldn't find it, but I suppose it's like the normal Wave, but with a 2 handed blade instead? ...
Since I'm gonna use it strictly for work use, OHO tools and knifes should be legal in Denmark, if I understand the law correctly. It just has the be stowed away, while moving to and from work, i.e. not in my pockets or directly on my person. I'm pretty sure AHB knows alot more about this than me.
