Don't know much about the brands you mentioned, but I can tell you civivi is good to go. Both of my civivis are great. Getting an Artisan Tradition here soon to see how it is, but from what I've heard and seen they're good too, and have a budget brand (cjrb) that's supposed to be as good as civivi (we knives budget brand). Just stick with one of the brands that is well known, and known to not lie about their materials. Eafengrow, no clue, but I believe they lie about the steel per luv them knives tests. Plus they ripped off the zt 0456, so I'll never buy one of their knives anyway.
