Thanks Neil. I completely forgot about the blackwashed 560. It looks outstanding! I have never owned a ZT but I have several Spyderco knives (Delica, PM2, Gayle Bradley). How does their fit/finish compare to Spyderco? And as far as size and pocketability, the Gayle Bradley folder isn't as heavy to me as people said and it appears to be somewhat comparable to the ZT. Did you have any problems carrying it?
Both Spyderco and ZT have very high quality fit and finish. I have yet to have a problem with either manufacturer and I must own a dozen from each, maybe more. My second Military should be delivered by Friday (got the fluted titanium).
I carry my "big" knife in my right back pocket. My Keychain Of D00m goes in my right front and it's death on knives, which is why I carry in my right back. Sometimes I'll carry a traditional or smaller knife in my watch pocket (today is a Kershaw Damascus Double Cross). So, a heavier folder doesn't really bother me. That said, if I'm wearing slacks, I go with something lighter, maybe a Military.

More seriously, a Benchmade 530 or a Kershaw Leek or a Spyderco Air would be my choices, maybe a traditional, depending.
Some guys carry a lot of stuff on them every day. I'm one, I suppose. Other guys don't like feeling weighed down with all that metal and I don't blame them a bit. Sometimes, it's what you have to wear for work. Lighter weight slacks are much less forgiving of a bigger knife than jeans. I'm lucky that I wear jeans at work most of the time.
I've carried everything from a Spyderco Micro Dyad to a Strider AR here at work and no one cares. Scared a customer once when I flicked out a ZT0777 M390 to cut a zip tie, but otherwise it's been a non-issue.
