The only reason I got that version is because it opens easier amd flexes better than titanium liners. It is made quite well and locks up tight with the steel liners. It is, also, much more economical.
It was conveyed to me that the ones with the titanium liners will eventually get lazy because of the nature of titanium used as liner locks for other knives. The "tsunami" function works well although not as well as a "wave" from what I have been informed of. Do not consider grinding down the surface of the quillons, if you get one, as they were made and meant to work that way for abrasiveness.
OBTW, only the titanium versions have AUS-8A blades. The zytel one uses 440A. Yes, the blade is not as good but for the price it is a worthy tradeoff. The blades are ground thin and roll or chip easily. I gather that the AUS-8A would be the same since Cold Steel seems to grind all their blades this way, anyways. Both a Vyager X2 folder I have with AUS-8A and the Zytel Ti Lite 440A blade do the same thing when used.
Other than that, get the Ti-Lite. COmments and remarks from people who I have shown it to have indicated it is very nice knife for the price and it is solid. Good luck!
