If knives are bad why are retail packaging and parcels so difficult to open with your bare hands?
The world continues to become more and more of a "p&ssified" place, or at least that's just the observation I've made over the past decade and a half or so. - at a very alarming pace.
Too many niceties, too many luxuries available to most in any developed country, that makes them take for granted things that not too long ago were only in one's imagination.
Needless to say I unapologetically carry whatever tool I see fit to carry (within my legal means of course), including not only a knife but a firearm as well.
Lastly, I feel this is only the start of your obsession, I think it will grow from here and before you know it you will need several shelves to house all your new acquisitions!
I'm more so in the stage of having found what works and what checks all the right boxes for me, obviously this will differ from person to person Depending on tons of variables including where you live and what you need your light for.
Today if I had to shed some lights from my collection and keep only 3 - I'd be keeping 2 malkoffs and 1 HDS rotary. Solid USA lights, that just seem to keep on working no matter what you throw at them.
