This knife is magnificent
I agree !
I've had one for several years (more recently I added the Techno; was surprised by how competently it cuts in spite of the thickish blade on such a small knife

).
In the same breath I have to say I don't "get" the fascination with the Bowie as far as it being a CUTTING TOOL. That exaggerated belly all up on the end of the knife is the last thing I would want in a gentleman's knife . . . for actual use.
Aesthetically , sure, it's a marvel with the contoured Ti and the polished blade. We get all that on the Swayback and the blade shape is far more useful.
The Bowie might be good for skinning but who would do that with that thin flat knife ?
I have no idea why it wasn't a bigger success.
From my initial experience one drawback is it is crazy hard to learn to open it like we do more "normal" Spydercos, meaning with one's thumb pad. In addition it is easy to press on the lock bar while opening it and add more resistance to opening it.
FINALLY I learned to stick my thumb nail into the Spyder hole and all becomes effortless and takes no concentration including flipping the blade out fast which I found to be impossible with my thumb pad.
Also the blade has no negative downward angle which is nice to have in a user but tends to be absent in a self defence knife. Examples that come to mind are the Spyderco Yojimbo and the Cold Steel Ti Lite.
Swaybacks tend to be at their best, I find , when cutting toward me, or lets say holding the edge toward me and pulling some kind of work away from me like cutting a leather belt in two lengthwise; so swaybacks , technically, are kind of specialized cutting tools.
that's my four cents, for what it's worth.
PS : I won't be selling or trading my Sayback / it's a keeper !
