Okay, I got the Rukus. I really like it. It is large. It opens so easily, it almost opens itself.
It is so smooth, that if you unlock it with one hand and your finger is over the blade recess in the handle, it can close on your finger and cut. It's sharp.
I would love to see another version, with a little more grip at the bottom of the handle. If it flared out just a little more, it would be even more secure in your hand. Having said that, it's still a comfortable grip.
Very nice knife.
