Here is a step by step mod with pics I did a long time ago. Not really anything big though. http://forum.multitool.org/index.php/topic,4579.msg74522.html#msg74522
what is the name of these screw? why LM utilize it? to prevent an disassembly of the tools for the warranty or other motivation?
Well you will need some security Torx bits like these (Image removed from quote.)(Image removed from quote.)(Image removed from quote.)You can get security bits from most big hardware stores or Ebay. That is the easy part , pulling a part a Leatherman Wave/Charge or Surge is no simple thing though , lots of small parts & washers .(Image removed from quote.)Bob's photo from this thread ------> http://forum.multitool.org/index.php/topic,2200.0.htmlThe earlier Leatherman MT's certainly are easier to work on, once you get those pesky knurled fasteners off.
If i understand you correctly, you would like to put that Chuck 1/4" Shank (never knew they existed, now I NEED one) on your Surge. You could grind the bit down to fit in the big bit driver, no modding of the Surge needed. I did something similar a wile back. I had loads of this adapters around so I played a bit. Works great.

Security torx is a joke. I just pop the little pin out of the star with a micro screwdriver and use a regular torx driver. Sometimes it even irks me that I have to dig one of those out so I get the Dremel and cut a slot for a flat driver. Then they can be taken apart with a SAK like everything should.
