The difference is the paddle stiffness of the Ripsaw( much stiffer) and the cobra is a 1 ply(?) vs the Ripsaw a 2 ply.How much different would a proposed 1.5" ice ripper be from the 1.6" ice cobra that is currently on the market? I put one on my sled and wanted it for that exact reason, extra paddle and just enough stud to add safety. So far, the 1.6" ice cobra has been great.
Good luck,
