I’m very excited about this Scrapper 5. What a great design!! I can’t wait!
As far as comparing it with the RMD without having an S5 in hand:
One of the things that I like best about the RMD is how the knife fits the hand in the choke-up position (finger in the choil and thumb on the spine) is just about perfect for whittling and fine knife work. We’ll see how the Scrapper 5 works out. I’m a little bit leery of that thumb brace on the spine for the above reasons.
