Can you groove a Case bolster right where you have the pivot pin?

thinking of experimenting with my peanut and tiny toothpick using a triangular file but the dimensions are very small. i don't think i can groove while fully avoiding the pivot. thoughts/experiences?
 
I´m with Mike. I wouldn´t risk it, I would also be afraid of loosening the pin.
 
I was thinking "why not", but they're right. You'd be filing off the swollen peened portion of the pin, and that's what keeps it from sliding out.
 
Of course you can. It will likely ruin the knife, but it is certainly possible.

Ditto to that.^

Most pivot pins are peened (flattened/widened/tapered thicker) at the ends to keep everything snug, and filing that off would remove the only thing keeping it all together. The holes drilled in the bolster are sometimes tapered to fit them (wide at the surface, narrowing closer to the liners underneath). That's essentially how knives that need rebuild/refurb are taken apart in the first place, by grinding/drilling or otherwise removing the peened end of the pin, so it can be pulled apart.

Here are a couple of GREAT illustrative photos of pivots in cross-section, showing the peened and/or tapered pivot pins.

A day late and a dollar short as usual, but,

when removing pieces of parts, removing a piece of the part which holds all the other parts together is usually a bad idea.
