Paul: That was me who dremeled off the sharp angle on the spine of the Calypso Jr. Unfortunately I don't have access to a scanner. Trust me, though, it looks fine. Kind of neat, actually, and comfy as heck. I can now cut hard materials with my finger or thumb on the spine. If I wanted to, I could polish area where I did the grinding to make it look like it was made that way, but I sort of like the funky customized look. This knife (as all of mine) is a user.
Take your time, when you grind. The steel is soft enough that it won't take you but a few minutes. If you have a fairly steady hand, you can sort of clean up your line as you go. I found it to be quite forgiving of minor boo-boos.
Have fun.
On the merits of the Vaquero Grande, please refer to my post in the other thread entitled "Six-inch Military".
