Green with a fully flat ground blade. Millie blade was a bit too big, Caly, Delica, etc a bit too small. I prefer a lockback to liner lock, though of all I've used Spyderco does the best liner lock. Had an FRN Endura a while back, much prefer G10 and didn't like the steep grind lines on it.
This thing is great. I will say, though, that it didn't come at the typical hair popping edge from the factory. Not a big deal as my Sharpmaker made quick work of it, but I've come to expect that scary sharp edge out of the box.
Either way, I haven't been this excited about a knife in a long time, and this isn't even one of the "premium" knives that I own either. I think it will be a great companion.
