Maybe it's part of growing up in a rural area, but we've always had guns and we always carry a knife. Now that I'm in college it goes with me everywhere, second nature, just like my wallet or phone or keys.
Pish! I live in a rural area and we don't carry around guns or knives! But then again this is England.
My friend has a few knives like yours. Notably that large hunting knife above the axe (which he also has). He has a few large knives, a flick knife, a taser, kubotans, nunchucks, some WW1 sword and a (legal) shotgun locked in the attic. I'll try and get a photo of it all.
