Randy,
The S5 was my first Bussekin, and remains one of my favorite designs. Its a perfect blend of size, weight, and blade profile. I had considered it strongly after I read MM's question.
Ultimately, I chose the ASH1 over it for a couple of reasons:
* The blade size and shape (slightly longer with a FFG and deeper belly)
* True full-tang construction (the knife might be called upon to be a very expensive pry bar in an emergency)
However, the S5 will always remain one of Dan's best designs. Its a great "if I could only have one knife" choice.
I'm trying to move toward "only INFI at 5 inches and over" so I'm keeping both of my S5LE's. I have one S5CG left, and finally made the tough decision to sell it.
If I could have two blades....
Busse ASH-1 and Busse NMFSH
If I could have three blades....
Swamp Warden, ASH-1 and NMFSH
If I could have four blades....
Swamp Warden, S5CG (since I'd have a 6" INFI I'd want the slicing ability of SR101), ASH-1, NMFSH
If I could have five blades....
Swamp Warden, S5CG, ASH-1, NMSFNO, NMFSH
If I could have six blades....
Swamp Warden, 411, S5CG, ASH-1, NMSFNO, NMFSH
I wouldn't need seven, because the above takes care of everything I use knives for.
