That post was one of mine, it was in the Knife Review section-I think. I'll tell it again and save you from having to search for it.
1. Contact BM and request another stud (tell them you want a replacement or just buy another).
2. Go to Radio Shack and pick up a a package of 2.5 mm diameter machine screws (if you have a problem tracking them down, let me know and I'll get you the product number).
3. Take one of the long machine screws and cut off a section of thread 5/16" long (no head on it).
4. Remove the single stud off the 750 with a spline key (I don't think torx or hex will work, but you could try. I got my splines from Jenson Tools).
5. Thread the just cut end of the machine screw into one of the studs. This may be a little tricky because of the burr from when it was cut, but it will go on with a little patience.
6. Insert the other end of the machine screw through the stud hole in the handle and screw on the other stud. Instant double stud.
Any questions or if I wasn't clear about anything feel free to email me. Hope this helps.
