DANGER: There is a risk of breaking your Leatherman. Do not insert the micro bit if it seems like it won't fit!
This "mod" is a jeweler's screwdriver with interchangeable micro bits (4mm), free if you already own the bits. [If you don't, you can get a very nice starter kit usually for under $10 for a set of 8 or so bits in a colored aluminum storage handle/screwdiver from various on line retailers. The Style CS works even better with these bits as opposed to the flat bits in my other video because it is a better friction fit with much less wobble. Be sure to push the bit all the way down so its bottom hits the main body as an end stop. Also note you are not wedging the bit all the way into the valley of the carabiner's metal, U-shaped channel . Attempting to do so will bend/break the Style CS since it is not actually 4mm wide, it is less, so don't do it!
Although you can mount the 4mm bits straight out the front like in my other video showing its use with Leatherman flat bits ,

, they also can be held at a right angle using the inside of the carabiner's "nose" (I just learned that term) as a back stop, but I find overall out the front is better; it may depend on the specific application though.
