I'm betting on Switch being the same as Xhair, Splice, etc. It's the small faceted one.
Four S is the same as Four, Twenty, etc.
I'm sorry, did I foget one? Hatchet is the same as Xhair, Splice, Five 2.0 and so on. I swapped Hatchet and Xhair icons and that's how all this started. XS Fice looks to be the same small faceted icon too.
Canteen is all alone for the moment until somehting else arrives with a tiny square icon.
Wires, that's a venture I was afraid to tackle. Most look like they could be the same.
