Snow/Ice Scraper

This is version 5 of my snow scraper designed in Fusion 360. The 1st was to sharp on all edges. 2nd was batter rounded but was very thin. 3rd was to sharp on the thumb grip. 4th needed to be resized. Please let me know what to improve upon for this project. :) P.S Also ask if you want to sell. I will probably say yes.
