Enlarging diameter of opening hole on a Spyderco

Anyone experienced in this? I have a Ulize that I like a lot, but my thumb slips out of/past the hole when I go to open it. I don't have the problem w/ Spydies w/ larger opening holes (Millie, etc.). I don't have access to a proper workshop or I'd have a go myself (and then probably come right back here whining for someone to undo the amateurish job).
 
I would think you could do the job with a Dremel but I would be afraid of putting the hole out of round by lingering too long one place. I would use the sanding drum in stead of a grinding bit to reduce over heating.
 
I was thinking of clamping it to a drill press & going low & slow w/ a larger bit.
 
It would need machining, not free handing with a Dremel or such. When (not if) you vary the vertical axis, then the edges will look uneven. Also, Squashfan pointed out the inevitable out of round from not moving consistently enough. Take it to some local machine shop. I've never heard of the factory doing anything like that. Expect the warranty to disappear like the metal your removing.

You won't be able to drill the hardened blade with a regular drill bit. You may be able to sand/grind the portion of the hole that your thumb hits to get a sharper corner on it for more traction.

I like that idea, I would think with a dremel, a guy could create uniform looking "grabbers" on the hole
