I had an original Wave as well. Good concept, but not robust enough for the real world. Gave it to a friend who's getting into this crazy/addictive/strangely sensible culture. No sense having it gather dust in a drawer; tools are meant to be used.

(Aside: one of the flat screwdrivers from the original Wave will fit a #2 Robertson perfectly, inserted crosswise. Go figure.)

The Wave II / ChargeXX is a huge improvement in design, effectiveness, and strength. It's twice the tool all around, with effective scissors to boot (first aid!). My only caveat is that I miss the long-nose Phillips screwdriver for electronics, which have deeply recessed screws.

You're right, the 420 stainless blades are adequate, but nothing special. If you can afford it, an upgrade is worthwhile.

None of my business, but FWIW, the retailer you name seems to be charging more than others. Then again, if you can catch a break on your favourite item, who cares?

Since you carry the titanium-handled items in a sheath, the size difference is irrelevant. It really does provide a positive grip in all conditions.

If you go for the TTI, be sure to post a review.

(I'm holding out for a Skeletool. Don't tell DW!)
