I have carried my Mnandi (#21 with Ziricote) every day for two years now. It has been used for a wide variety of things, amongst which are opening mail, boxes, dog food packets, clamshell packaging; cutting fruit, jerky, steak (some of those restaurant steak knives are awful!), brownies, threads, tags; trimming tomato plants, roses, stuff in the yard; it has been through the wash in my jeans pocket (not the drier, mind you!); I have used it in food preparation at friends houses where their kitchen knives are dull.
Just last weekend, I used it to scrape off the tatty "God Bless America" sticker that was on the back window of my car so I could put up a new one. That sticker stuck tighter than paint - I have never struggled so hard to remove a simple sticker! My Mnandi was covered with WD40, disintegrated sticker and as yucky as you can imagine. It did a great job on the sticker (didn't scratch the window) and when I was done, I just washed it - under running warm water - with some diswasher detergent, dried it off and it was perfect. I have never had the knife serviced and have only had Bryan sharpen it twice - the second time was after the sticker episode. The lockup is a solid as it was on day 1, it has a few character scratches and I just love it!
I take it out often to show people in response to the question "what kind of business?"!! The thumb notch works great - sure it is not a super fast opener, but it was not exactly designed to be used in a back alley knife fight. My life mostly revolves around a regular city environment - household, school, groceries, post office, bank - I don't frequent back alleys much!
To the best of our knowledge, no inlay has broken on side of the locking bar with the exception of Anthony Cheeseboro's knife that got run over by a variety of trucks.
Just thought you'd like some input from a regular user!!
