I like it, but if I pick up one of the M&G versions, it'll probably be the jigged bone.
I've found the comments on the "perfect action" of this run of #15's interesting. I've received a jigged bone and Ebony from the "standard" single-spear run so far, and both are what I would call "mushy" or "sluggish" in at least in one part of the action. My jigged bone is sluggish going from half-stop to closed, and the Ebony is the same going from half-stop to open. I'm hoping a good flush and oiling will take care of it, but it's definitely a new experience for me with GEC. Having handled maybe 80 or so GEC knives since I started buying them a few years ago, these are the first I've had where you could get the blade to stay in either of these positions.
(Sorry for the poor quality photo, just snapped one real quick to show what I'm talking about.)
