I believe you can build your own Gerber 600 but not the newer Gerber Legend 800.<br><br>I've read through searching the usenet groups that one small retailer was replacing the bottle opener with a bottle opener/can opener combo for free when they first came out; but that wasn't in the U.S. Anyway, since the Gerber can be taken apart easily (as I understand, they incorporate torx fasteners), I would think a knife retailer could easily replace any of the blades as long as the parts could be ordered. However, this seems to be a lot of effort just to get it exactly how you want it.<br><br>
