Welcome and since you are comparing your rats to other knives I will add my recent comparison on your thread. I purchased a RC- 3 a short while back and promised a review compared with a fallkniven F1 when I went camping with my son. So here it is. I must first say that it was not a side by side comparison it was basically I on a 3 day trip I used the rat the first day for whatever the fallkniven thesecond and the rat on the 3rd. During this time I used both for cutting vegetables (onions,tomatoes), cheese, meat(dried beef) nylon rope, cleaned 2 medium 1 small fish, and whittled two sets of chop sticks just to get some wood work in. I must say that I found both knives fully up to the task of all the jobs set before it. Now on personal likes and dislikes. I really like the ergonomics of the RC3 better. It fits my hand perfectly and I like the way the handle design acts as a finger gaurd to insure my hand does not hit the blade. I also like that if I choose to I can use the curve in the choil as a finger groove and choke up for better control on push cuts (I used this method on the chop sticks). The rats thinness made it a slightly better slicer than the fallkniven which was not slouch by far. Its just that on softer items like the cheese the fallkniven did not cut as smoothly. Both cleaned fish well and both sliced ropes without any needs for touch ups. Being 1095 I did notice even after wiping dry on the uncoated part of the blade when I got home on day 3. Both had good edge retention and I did not need to touch up either knife. Now for my conclusions:
I believe that overall the RC3 won simply if for no other reason it was more comfortable to work with. The RC3 did show signs of rust because I did not use any oil while out in the field, on that note I wanted to know what it would be like under true field conditions where I might not be able to oil my knife after every use. This small amount of rust did not affect its cutting ability any though. The fallkniven I think slightly shines on the simple fact that it has a slightly longer and narrower blade and I think for general utility this serves a better purpose along with its better corrosion resistant qualities. My theory is if a knife is a working knife then it must be comfortable and when all else is considered when comparing equal or similar knives the comfort factor is what will win a victory every time. When hands were wet I found the RC3's grip to be better than the fallkniven.
So my breakdown is this
Fallkniven(things better than RC3)- better rust resistance, more edge, narrower profile, easier to conseal for everyday carry.
RC3 (things better than F1)- handle safety(keeping fingers of blade), better slicer due to thin profile, warmer union between hand and handle, shorter legal in places the F1 might not be, a true EDC.
