I'm afraid I've not much use for most of the "modern" Case knives using stainless steel. The steel is that "surgical" stainless, i.e. 420 or one of its crappy clones. I've two new Cases that were given to me as gifts(what do you give a knifemaker?-----storebought knives of course). One is a trapper and the other is a two bladed muskrat. The steel in both of them truly sucks. Neither one holds an edge for very long, and I don't like carrying a knife I have to sharpen constantly
Also, I think the fit/finish on them is......adequate, but not nearly as good as the older(pre WW-II) ones. The muskrat lost its logo that was glued(?) into the scales; it was one of those "one of 2500" collectibles. Not being a collector, I used it. If I was going to invest that much money in a factory knife; the prices I've seen on the xx changer range from around $60-120, I'd surely opt for a blade with much better steel and workmanship....one of the many EXCELLANT Japanese blades for instance. The Japanese have a POWERFUL knife/sword making tradition that borders on the spiritual.....been a lot of years since I saw a bad Japanese knife. The German Company Boker is producing a folder using 440V stainless/titanium handles for around $74.00 that would work "down under" since you all don't have our cold winters. Last, and most probably least important of all, I don't find the xx-changer or their equivlants very appealing. The designs are necessarily on the weak side, which is no big thing if you just cut with them, but I pride myself on being able to use ONE Blade well. A good knife made with a good steel is better than a medicore one equipped with multiple blades of poor quality materials. The idea of the saw is a good one, though. I carry a small gerber saw in my hunting game pouch.
