I love my RC-4 and it goes everywhere I go, BUT it travels in my day pack. I don't wear it on my person. When i get my RP knife, that will ride on my belt everywhere. As much as i hate to admit it, I think that the RC-4 is just slightly too bulky to ride on the belt everywhere and the RC-3 is perfect. The only reason that I had not previously purchased an RC-3 was because i had the RC-4 and just couldn't justify (with the money situation these days) purchasing another RC knife that was so similar without some special circumstances. Now that there are RP RC-3's, I had reason that outweighed the money situation. I am foregoing quite a few packs of Ramen noodles for these knives. If you want the best all around pack knife that can also be worn when in the bush, go with the RC-4. If you want the knife that you can wear 24/7 and still be one of the most useful knives you'll ever own, go with the RC-3. These are just my opinions.
