I'm gonna go and recommend yet another Kershaw, my favorite one, which ticks most of your boxes too:
The Kershaw OSO SWEET
- Flipper and would prefer no thumbstuds, just flipper open
Manual flipper, no thumb studs, SpeedSafe assist works flawlessly
- Blade of 3" or less
Just a hair over 3" (3.1")
- 3 ounces or lighter (Kryo feels just a bit heavy when carrying on my khaki pants)
2.9 oz., just unnoticeable
- $100 or less
$20-25 at most places, and it's very easy to find
- and preferably Deep Pocket Carry
Not deep pocket carry, but it's pocket clip is excellent, discreet and makes it really nice to carry and use. A true favorite!
