Relocating the pocket clip on a BM 520?

[BLM4L]

I just got a BM 520. The pocket clip is on upside down from what I am used to. I can tell from the the 3 holes on the opposite end that it is meant to be relocated but not sure what to call the tool loosen the clip.
Any suggestions?

It most likely a torx bit that you need. I got this set from Lowe's:

It has all of the bit sizes that I need for all of my knives.
