Good thinking HD I love my Mudder handle on my SS4 and a grey blade would look cool. One thing I like about the current line is you can actually own the whole line up without taking out a second mortgage. All I need is an S6 preferably a LE.
I consider that if 2 knives are released at the same time like the Hook and guard or the S6 and S6 LE they are options not different knives so you should only need one.
