Case Devil's brigade Stiletto or Lewis/J. Nowil

[Tzvi]

I'm in the market for a mid range S/F dagger and was wondering if anyone here had an opinion on the Case "devils brigade" stiletto Vs. a Lewis/J. Nowil Sykes production.

Specificly is one sronger than the other? does one offer a better edge to sharpen, or do both pretty much act only as a Stiletto?

Any experiances either in use, or even handling would be appreciated.
