My 3 favorite knives are Randall Randall and Randall. I use every single Randall I acquire . My dad gave me my first Randall in 1978,2nd in 79. It is a model 3 with a 5 inch blade. Used it last month to gut a 7pt Fla whitetail as well as an 8pt Montana whitetail in 05.My model 3 has taken hogs, gators, deer, fish, coons etc to task and held up fine. I like the blade. I think 6 inch is a bit much. You won't gain anything. The model 3 5 inch is very nicely balanced and "feels" right. I also like the model 11(Jay Campbell's blade of choice)4 inch. The Trapper model 25 is a nice drop point in a 5 inch blade and the 26 is much the same in a 4 inch blade.
You cannot go wrong with a Randall model 3 and if you don't like it , call me.
Give your knife some "soul" and use it. Are they the best? I don't know, sharp steel is sharp steel. They have a good balance to them and are designed with hard use in mind. The 3 allows you plenty of curve for skinning but enough straight edge for heavier duty. A great all around knife and a perenial classic.
Otto, you're still my hero.
