There are a few things you can do: 1- First thing I would do if in this situation, try a #7 torx driver and really apply some pressure. 2- If that didn't work I would take a flat edge screwdriver, pad it, and insert it in between the handle halves, as close to the screw as possible, and apply pressure while trying to unscrew the screw. 3- Anothet thing i have done is to use my dremel tool with a thin cut off wheel and CAREFULLY cut a groove across the screw head, then use a flat screwdriver to remove it. I have used all three methods and all three have worked at various times. One very important thing is to heat the screw to soften the loctite. I usually put the entire knife in a pot of boiling water for 5 to 10 minutes. You can also use a hairdryer or heat gun. Let us know how it goes.
