The HD-7 is really a nice knife & what I liked in it over the SnG, is its narrowness in the pocket (The wave feature didn't hurt, either). My only problem with it is that darn chisel grind. I understand it for SD & carried a CQC-7 for yrs when I was in Patrol (The chisel grind does allow for an incredibly sharp edge & it's great for SD), but outside of that, I prefer other knives (& other Emersons).
However, in comparing the 2, I think the HD-7 definitely holds its own against the Strider & other HD folders.
Oh yeah, I've heard from someone that should know, that Emerson is not planning on mass producing the frame-locks anymore (I would guess that's the HD-7 & CQC-12, right?).
