I think everybody should have some form of personal illumination, even if it's just a keychain light. I also think that everybody should have at least a Victorinox Classic on their keychain, if not a larger pocket knife. That way, everybody who doesn't "need" to carry one can stop bugging me to borrow mine. :laughing:
As for a real, "nice" flashlight, yes I need one. I'm nocturnal. I wake up at 4pm, go to work, and go home around 4am. I'm asleep most of the time that the sun is up. Add this to the fact that my transportation is pedal-power, a bright bikelight is essential, as is an EDC flashlight.
Do I "NEED" a $140, or even a $300+ flashlight (which I'll have when the HDS U85 is available again)? I suppose not, but I appreciate quality and reliability. Which is why most of my pocket knives are similarily priced. I could make do with a Nuwaii, but I prefer an HDS. I could make do with a $50 Spyderco (actually, I do, but that's my secondary carry), but I carry $110 Benchmade 710HS, $150 BM42MC, $400 Microtech Scarab, $250 MT LCC D/A, or most recently, a $245 Bradley Mayhem balisong.
There's people I know who think I'm crazy, but these are the same that put $2000 worth of rims on their crappy car, change cell phones every 2 months, wear $60 shirts, etc. Two different kinds of people, two different causes for credit card debt.
