Bill, the only things about it that some folks may not be in favor of:
Size, it is pretty small Gents knife. So if you have some big ole meat puppets for hands, it could get lost. But if you buy it, you likely don't plan to chop 2x4s with it anyways.
One hand opening, you can do it. It just takes some practice. At first, I didn't know you could. Then I found a video of a fellow doing it. It was a face palm moment. It is easy.
Reality for me, is I enjoy opening it with two hands. The whole process of drawing it, opening it slowly, then cutting a 2" thick slab of mignon at Ruths Chris is a dream.
Thinking about Mnandi vs Small Seb. You can take the Mnandi on a date with a super model. You can bring the Seb on a date with the chic from the Whitesnake video. They are both gonna cut with quality and feel bank vault solid. One has more panache, the other is a little gaucherie.
Thats about all I can think of. I suggest adding a leather lanyard. It helps remind you that it is clipped to your pocket.
There are two different versions I am aware of. The main difference is a subtle size or design of the nail knick. Honestly, I couldn't even tell you which model mine is.
The knife is very very smooth. When it locks open, it makes a addictive clack sound. It is surprisingly loud actually.
