there is a mod here i saw done that adds a scissors to the skeletool, looked quite nice. I believe it would be possible to remove knife and do the same thing.
that said the blade on the skeletool is a nice shape and comfortable to use...a person can't have too many blades on person
but i understand the sentiment, I replaced the main blade with tools on a couple of my saks because i carry a dedicated blade as well and i wasn't using them.
i edc my skeletool along with dedicated blade and it's my backup,,,,
