WJC01:
I have an Ontario made RAT 5 with that R on the handle.
Don't know what it means either,but I haven't had any issues with it:
I've also had in the past a RAT 3 D2 , TAK 1 & a RTAK-all made by Ontario & traded them all away.
This one might be going away soon too.
Because.....
I got THIS one in the mail just this morning & been pounding on it since then:
With the rest of the crew:
As has been said many times before , the quality of the Rowan made knives is well worth the little extra money they cost.
It's one thing (and very much appreciated) to read about the differences in quality,fit & finish,sheathing etc. , but when you put them side by side with each other it's real obvious that the RC blades are very much worth the price.
