So, not the wave. It's junk. I broke it prying with less lateral force than I apply to my butter knife when I spread chunky peanut butter on my toast. The tip of the knife is also bent, and the ergonomics are awful.
Sorry to learn of your problems with the wave. I have had great results with mine over the years. A multitool is what it is. It is a compromise. I have seen none that have accomidating ergonomics and none that can stand up to any sort of extreme use. They are what they are.
