The Umnumzaan is my ultimate, and favorite folder for EDC... I have been around the block so to speak, and the umnumzaan is what I ended up with. I have been EDC'ing it for a couple years, and it is just fantastic. Both as a work knife, and a lighter duty EDC. I am so happy with the umnumzaan in fact, that I have since sold off all my other EDC type knives, except for my Murray Carter neck knife.
I no longer feel the need for another folder. I am completely happy with it. The semi sharpened swedge is great for all sorts of things, like opening packages, scraping stuff, striking a firesteel, you name it. It essentially functions like a heavy duty utility edge. I used it with drywall, and I think the swedge is perfect for scoring and shaping it. Also, unless your planning on spine whacking your umnumzaan repeatedly, the lock is plenty strong enough (I can't think of any practical reason for spine whacking a knife, so you'll be fine.)
I have compared this to all the common choices (and many not so common) and just love it. Its not too heavy to actually have with you all the time, but it is big enough to handle most jobs with ease. It is a little rough handled for long term bushcraft usage, but if you want to do that, get the right tool, and get a fixed blade with a good ergonomic contour to the handle.
To sum, the umnumzaan is my absolute favorite folding knife. This is such a hit or miss knife, that the only way to know is to try it yourself. I strongly suggest giving it a go. And dont give up on it just because it feels a little hard to open at first, you can customize the pivot tension and lock it in with lok-tite. That's one of the perks of the design.
So should you get an umnumzaan? Yes
