I am on my 3rd Wave. I have returned 2 in 20 years after snapping blades which they replaced without quibble. The replacements have been refurbs though and I don't really use the current one as it is very stiff to open. Nowhere near as ergonomic as the original. Currently the small glasses screwdriver is snapped on it after I tried using it as a bradawlI have the wave, most excellent tool!
