I'll be looking forward to the progress updates too Oh, and if you're serious on the spare wrench ...
I'm always a fan of voiding warranties and butchering tools to suit ones needs!
It came standard on this MP 600 - I believe it´s called the Scout. The file has a diamond coated side and the awl is quite good.
I think it will not work well.The handle on the PC is wider and has no locktabs, so the Clip must be ground slimmer.The Gerber has one fixed and one screwed pin on the pivot, but the screwed pin is on the right handle side, so the clip has teh wrong form.I guess a straight, slim clip from a knife will be an easier mod.
