Hi guys. I'm planning to do my first mod I'd like to swap the knife for a serrated blade on my LM Blast like the one from the rebar because I always have my Spyderco Polestar on me so it's redundant. I'd also like to exchange the small flathead for a reamer/awl. Just wondering if anyone's tried it before, and also how can I remove these screws on the handle??Thanks
