The Sebenza looks to have a secure locking system and I hear that it is extremely well made. However, it doesn't look to have a very deep finger groove. I think that I would have some concerns about my hand sliding up the blade, especially if I were using a natural grip.
I'm considering giving the Pocket Hobbit a try. Does anyone on the forum have one? I wonder how well it works in the forward grip. I'd also be more inclined to carrying a folder openly on my belt than a fixed blade. I wonder if it's small enough to fit in my Aker in the pocket knife holster.
