I've carried both the New Wave and the new TTi Charge at least a year (each). The price is pretty much double for the titanium. I find the Charge to be just as heavy despite use of titanium in the handle. The cost buys you the hook, the better steel in the knife, and not a lot else, although the special tin I got it in had a clip, a lanyard eye (though a bit sharp for direct-tie - use a keychain) and one plastic magazine full of the most common driver bits.

So, if you don't plan on using the clip, that's really a wash for value. You can probably pick up the Wave for $65 if you look around and the TTi for double that. So you get half of the $15 set of bits included in that price.

I've EDC's both. I've switched to the TTI, but to be honest, it now seems like a bit of a waste. The knife on the New Wave is really quite nice considering. Unless you hunt or have some special need, the gut hook is maybe only useful for cordage now and then.

If you aren't a hard-core knife enthusiast/user, stick with the New Wave and get the set of bits if you need them. Spend the extra cash on Doug's Photon or save it toward one of his knives. But either way you go, both are rock solid performers. I'd take either one.

EDIT: Okay, the TTi hasn't been with me quite a year yet, but I've had it since the first came out.
