It’s hard to beat the size and weight of a PM2. I have a 0350 and a 0560, but they seldom get carried due to their size and weight. I think the ZT knives are great outdoor knives, but the PM2 is just about the perfect EDC knife.
Have you considered custom scales for your Griptilian? I have 4 with WilkinsGrips scales and love them. I’ve gone through Spyderco and ZT phases, came back to the Grips with scales.
Spyderco PM2 IS great. The Spyderco Gayle Bradley might be tied for my favorite and may be a tougher overall knife. Manix 2 is great also.
Benchmade 710 is a great knife.
Strider SnG and SMF are my favorites.
I have a ZT 0566. It’s an okay knife overall. But compared to the other ZT knives I have, it is the weakest in several regards. One of the biggest is the AO action. It is horribly weak, even when compared to my plain old Kershaw knives.
Get the ZT 0562 instead. I like the grip of the regular one with G10 scales over the carbon fiber.
