I used to carry a Buck 110
Then I discovered thin blades like this (less than 2mm thick at the spine for a four inch blade).
"Ah ha!" that cuts through stuff with much less effort and more control.

Oh I have had lots of "Ah ha !" moments.
ESPECIALLY AFTER JOINING THIS FORUM !
. . . next one came when I discovered this handle shape

. . . in this length. See how it fits my hand. "Ah ha!"

. . . another when I discovered this handle material
and handle sculpting
DOUBLE FREEKIN' "Ah ha!"

So the material wears or breaks down. I made it replaceable (see photo below) so . . . duh.
Then I discovered this blade shape "Ah ha!"

The Thinned Ti Lite spear blade was good; this is better especially when it angles down from the handle like the top knife (Case Trapper).

Oh no . . . don't go away . . . there's more :
This was a big one . . . M4 steel and not just any M4 but Spyderco's M4.
"Ah ha!"

I mean I suppose maybe someone, some where, is doing it better but DangDigidy Spyderco's acts, for me, like a steel alloy formed in Heaven so I don't need or want anything "better". Easy to sharpen and cuts for ever in really challenging materials.
Oh yes and I may as well add the "Ah ha!"

of the blade that is thin behind the edge i.e. the Gayle Bradley . . . one of the three below (still
BETTER than just a knife with a thin spine).

now if I could just get these few small things in one knife . . .
. . . ah . . . but this isn't heaven is it.
