Would the SS4 allow you to do both large and small game almost as well as the muck for large and the bdle for small or is that wishful thinking? From the looks of it, for me, it seems like the SS4 would be a better single knife choice if your brother hunts all size ranges. It would be more than tough enough for breaking up a pelvis and would still function well in a coping role. I am not a hunter so this is purely speculation on my part but I am hoping it does not detract from the conversation.
Like Toast says, I wonder if the SS4 would be a better all round knife for the tasks at hand???
I don't hunt, but do fish, and I love my SS4 for that. My step-son uses his Busse AD for his fishing knife.
It works great too.
Just a note though, I also have my ScrapMuk, and I love it as well.
Cheers
