Just got my Yari and have not had the chance to edge test it yet, but here are a coupla observations.
The Yari has a thinner edge than the lg. Nimravus. This is because the Yari has a higher grind than the Nimravus.
The handle is slightly curved which makes it more comfortsble in my hand. Handles are actually about the same thickness. The index finger cutouts are about the same depth on both models.
My Yari has a 1/2" longer blade than the Nimravus and has more of a taper out toward the tip. Both knives are 1/8" thick at the spine.
IMO, these two knives could be brothers, they look so much alike. They both have well done Kydex (Nimravus) and Concealex (Yari) [methinks] sheaths.
Out of the two, right now I prefer the Yari as it seems to fit my needs better than the Nimravus, but by the slimmest of margins.
I hope this helps a little and my apologies for not having any cutting info to share with you.
