Without handling the S5, I have reason to believe it will be one of the most useful knives I know of. It looks as close to perfect for functional size and design with the mudder handle.

I really like the SOD, I don't see any big upside in the Regulator owning the SOD. To me it will not likley be a great slicer, or nimble knife even though it is perhaps better balanced in the hand then the SOD. I think the balance being closer to the handle would make it a weaker chopper. To me, it looks like a tweener not likley to be great at anything, but we will have to see what the experts say.

I think having the 5" S5, the 7" SOD, and obtaining the DF....would set anyone well for any occasion.....ok, a SY Bolo Machete would round things out nicely.
