I am a military/Cold War veteran.
There are knives, and there are knives.
There are the all category, make, style, and material ‘kitchen’ knives. Believe it or not, THIS is what England wishes to regulate!!
Then, in their own class, are the Kabar (Sir! yes sir!), the Faibairn-Sykes, and the Case V42.
Yes, there are ‘more portable’ models, but with the two aforementioned categories, there is enough to talk about.
