I bought several Benchmade knives before I found out about the Ritter versions.
I love my 154CM Mini-Grip with the sheepsfoot blade. That led me to order the standard fixed Griptilian with the 154CM blade. I had no problem with the steel or edge holding capability of that knife, but I hated the cheesy nylon sheath and the fact that the full tang metal is "proud" (extends beyond) the scales all the way around - can you say "full circumference hot-spot?" It was not for me, but I gave that knife to a friend and he loves it - great.
After I learned about the Ritter MK 3 version, I researched it and found that it kept what I liked about the standard fixed-grip, but corrected most of the shortcomings. I really like the lightly machined textured G-10 scales. S-30V and the stonewashed finish is definitely an upgrade. The first knife I ordered showed up duller than any Benchmade I ever owned, so I returned it for an exchange. The second knife was much sharper and I kept it. The only thing that I didn't like was the sheath. It is a nylon sheath that is definitely better quality than the one supplied with the standard Fixed-Grip, but still not what I wanted. After some more internet research, I ended up ordering a right-side vertical kydex sheath with Tek-Lok from Brian at
www.okuden.net for $65. After I received this sheath and mounted a firesteel loop, I finally felt like I had a great package. The knife is solid and light-weight for it's size. Using information I learned from this site, I hand-convexed the edge using sandpaper with leather backing and stropping. Now you are really talking about a nice package.
I am a big Bark River fan for most things since they come with great convexed edges and nice Sharpshooter sheaths. Having said that, if I was asked to pick an all-around set of knives to do everything I do, I would choose the following four knives:
1) Small - RAT Izulu (with hand-convexed edge)
2) Medium - Ritter Mk 3 (with hand-convexed edge and Okuden kydex sheath)
3) Large - Busse NMSFNO (hand-convexed edge & Mashed-Cat kydex sheath)
4) Chopping - Bark River Golok (with optional EEP treated leather sheath)
These four may not work for you, but they are all proven choices for my realistic needs.
Good luck with your choice(s).
