I currently own the wave and have had it for years and I love it. I was recently made aware of the surge and the giant scissors and changeable saw blades are super slick. Is it worth purchasing the surge for those features or should I stick with the wave? Is there something else I should be looking at? Have you seen people stuff any cool shit into the t slot thing? I am basically trying to just spending 120 dollars on a multitool when I already have a 120 dollar multi tool that does basically the same shit
