I actually have a device designed for single pin that is very similar to the mechanical pencil, My problem is that it has such a long lever arm that it’s easy to apply too much force, If using that, grab the pencil as close to the chip as comfortable for better control of force and distance.

I like to use a pocket knife blade. It’s stiffer and you get better control (the razor blade is more flexible at the pointy end. Also the knife handle allows better control over force as you are rotating, rather than levering.

Be carefule in step 4, the red circled connector’s other side is attached by a pair of small plastic hooks to the motherboard. One of the hooks is very small and can be easily bent if that side comes off and has to be reattached.
