Thinking out loud, speculating...

The CC with "serrations" might be nifty for boaters, etc., since the size is more convenient than some of the other exposed tang RMKs.

Why serrations? Some of the styles of serrations on the market (think Spyderco) are super sharp and "cut both ways" if you have to cut a rope.

The RMK saw teeth were designed for ripping--aluminum and Plexiglass--and are ideal for that.

David, the diver, who I have not seen on here for some time, might have some real world experience with both saw teeth and serrations Maybe he will see this and respond.
