That's interesting. The Mini Rukus looks like it's thicker than the Grip. I have a few Grips and like 'em. I found after removing the clips, they're an easier fit in my hand.
I'm in the trades. I use an old 550 440c model for trim work, and have S30V and M2 Versions of the Ritter. To save the knife from the keys in the pocket I use a large BM sheath for EDC.
The 610's too big for me, but I do have one of the 615's on the 'list'. Question is: what sheath fits this one?
