The Bravo 1 is an amazing knife but it is thick...damn near a prybar. For a 4.25" blade it is .215" thick!!!! The RC4 is 4.5" long and .188" thick. I have a Bravo 1 and had a RC4. I really like the grip on the Bravo 1 a lot but it does have some drawbacks too. Here's what I like first, better contour, bigger, less boxes design. It is a more comfortable handle without a doubt!! Now the bad, it has a wax polish on the micarta. I do not like a shiny pretty finish on a survival/bushcraft knife...If I want a polished finish I'll buy a steak knife!! Just reminds me too much of a kitchen knife...Just my opinion, other might love it. Also sweaty grip seemed to be better on the RC4...but I didnt have a ton of time to really make that a substantial conclusion. Also being thicker makes fine tasks a little harder (the convex grind offsets this to a degree), not much but still harder. This is my opinion after using both...I use the Bravo 1 far more but that is because it is what I still have. I also like the convex grind better. And one final note the Steel...IMHO is better as well. The Bravo is the more durable of the bunch. It really is a tank!!! At this length it could be the toughest knife around. The warranties are very similar for both. Mike is a very nice guy at Bark River. If you ever get him on the phone you can easily talk to him for 30+ minutes!! Customer service at both are very good!! Warranty is a wash. So as it stands I like the Bravo 1 better but let me continue. I do like a lot about the RC4 too. For one the Price, $50-70 cheaper!!!! The choil, it really offers nice gripping for fine work and other tasks...I really like it!! The thumb serration are really nice...I really do like them as well and they are comfortable. I love them on my RC6 a lot!! Next, The RC4 sheath system is far far better, more mounting option, just a lot better overall. Tremendous amount of possibilities. The Bravo 1 sheath is not so good. It rides high on the belt and doesnt offer many mounting options. It is alos stiff as a board!!! Even after drawing it out several times. It is so stiff it takes two hands to put it back most times! But back to the RC4, I also prefer the matte micarta grip finish (not necessarily the grip itself but the finish) compared to the waxy polished bravo 1. You can get a good grip for fine work with the RC4 as I stated. I also like the exposed pommel. The Bravo 1 handle might feel a little big for some for a knife at that length which might make it less maneuverable for fine work (once again IMHO). I felt I could do fine work easier on the RC4..but much that has to do with the Choil. I do not care for thumb ramp on the Bravo 1 at all!!!! It is sharp and I know you are suppose to put your thumb on the other side of the serration on the down side of the ramp...but I still dont like it! It has its function but I dont care for it much. You can order the Bravo 1 without the thumb ramp but it is hard to find. You can send it in as well..but that is 12 additional bucks to spend it and have it returned. Both blades have their pluses and minuses. I will probably get another RC4 at some point. I do find myself missing it, especially the sheath!!! It is really a nice knife. This is the break down. If you want a tank (better steel, better grind)...get the Bravo. If you want a mount everywhere with well balanced performance across the board, get the RC4. Either will not disappoint.
