With the talk about choils and detail work lately, I was curious about something.
I see a lot of people post pictures of them using this grip:
I generally do not use this grip, because I find it uncomfortable for my thumb. Most Spyderco knives don't give my thumb enough room to comfortably extend to the thumb ramp while using the index choil.
Now on the Calypso I can scoot my hand back a bit and make that grip work for me. Same thing with my Police folders:
But this isn't possible to do on many of the smaller designs that rely on a choil for a four finger grip.
This is one of the reasons you don't see me carrying designs like the Dragonfly, because they don't offer much in the way of alternatives for my grip.
I suppose I could wrap my thumb around their handles, but then cutting feels less precise, which negates one of the big draws of a smaller knife. I could also put my thumb on the spine, but then it's going to get in the way of what I'm cutting.
On my larger knives like the Calypso, Manix XL, Military and Police, I prefer gripping them behind the choil. The rare times I utilize the index choil, my thumb does not use the ramp.
Over the years I've realized that the most ergonomic Spydercos have my thumb extend about an inch past my index finger, and designs that don't allow that rarely stick around for me.
For me, the ability to extend my thumb like in the above picture is a requirement for good ergonomics. I voted no.
