When you do a Spyderco blade on a SAK it usually takes its own layer because the blades are meant to be centered. On a 91mm compact it would be possible to use a Spyderco Grasshopper blade with the combo tool in the same layer. The Grasshoppers blade is not as stout as a D Fly or a Delica but if you could find one in 12c27 Sandvik it would be worth it but they are getting harder to find because they have switched steel to 3Cr
