The B4 is really, really, really amazing!!!! I can't stress enough how much I like the B4. It's be far the best 4" blade I've ever owned.

Thanks for the comparison shots! I just bought three pricey pieces of satin INFI in the last couple of days, but when the dust settles, I am going to get the R4 & 3-11. Your thread definitely pushed me over the edge. I am a big fan of the Rodent 9, so I think I will really like the R4 handle based on your shots. My hands are smaller than yours and the Rodent 9 handle, while great, is just a bit on the large size. I agree that the handle design really works well in the choked up position. It also works well choked back for chopping. I can see that the same is true, at least with choking up and using the choil for detail work.
