I’ve carried a knife in my pocket everyday for the past 35 years or so. It’s a useful tool both for actual work and mundane tasks like opening boxes/etc.
A few weeks ago I was hiking near a lake and found a bird entangled in fishing line. It would’ve been very difficult to free it without some type of blade. Hell, it took almost 15 minutes even with the knife because it was so wrapped up and distressed.
Ah yeah, that makes sense. There’s a big difference between a 7cm folding pocket knife and a 20cm fixed blade rambo-esque hunting knife… And I can’t think of any reason to carry the latter around in a city : )
