I have two older Waves and one TI. I like the TI better. When I used the screwdrivers on the old wave on a tight screw, I twisted the screwdrivers like a cork screw. The new TI screwdriver is a lot stronger. The locking screwdrivers on the new TI do not collapse like the non-locking ones on the older wave. On the old wave, the hole used to open the knife blade is smaller then the new TI, and I cut my thumb a couple of times opening the old wave's blades. With the larger hole on the new TI, I have not yet cut my thumb. The old wave blades required sharpening more often then the new TI, when cutting a lot of cardboard boxes. The scissors on the old wave is larger than the new TI, but both have worked well for cutting paper and string. The pliers, saw, and file on both are all good.
