My thoughts on the R4....

-Very secure when choked down for light chopping.
-Feels great choked up for finer tasks.
-Feels great in hand in the standard grip.
-Compact enough to comfortably carry.
-Weighs around 8 oz.
-Convex Saber Grind makes a lot of sense for SR-101.
-Great balance in the hand.
-More capable than Rodent Solution.
-Makes a great hunting knife.

The only reason I let it go was because it wasn't INFI, otherwise I really liked the design.

The only reason I would choose the Rodent Solutions over the R4 would be blade length restrictions...
