Just to add a bit about tip up/down:
I carry tip-up if possible. I tuck th eknife to the side of my pocket, which helps keep the knfie closed. I had a tip-down AFCK from benchmade poke holes in a pair of pants and poek me in the leg which opened a bit in my pocket!
Personally, I find the tip-up safer that way given how I carry though. I frequently check my EDC to amke sure it is tucked right to the side of my pocket too.
Also, I read a psot by mick Strider noting that, at least has he beleves, tip down can be more dangerous in a vehicle crash, as if the blade is opened a bit (as mine was) or does open in the crash, it can puncture your leg more easily. Maybe true, maybe not, but was food for thought to me.
tip up/down has a bazillion posts on the forus though, so a search could yeild hours, no DAYS of reading I'm sure
I agree that the new style is more functional for the broad public. It would be a bad business decision though to make runs of knvies with separate tip up and tip down, left and right carry. That would add to the cost fo the knvies for sure.
