With that in mind (a "configure your own SAK" module), Victorinox should try to standardize the implements (thickness, shape, etc.) so that all tools can be combined any way you want (Victorinox would then send all the parts to Neil anyway )
When I met with the Victorinox-Crew in summer (http://forum.multitool.org/index.php/topic,21438.msg398411.html#msg398411 ), I mentioned the hickups as well.They told me, they were working on it, but it will take time, as there are more pressing things in the work...
