I have an original. I cut my teeth at an angle about 1 week after receiving it and it was a MAJOR upgrade (LWCG knew it was too after the pictures, video and phone conversation, but that is neither here nor there). Personally I would recommend cutting them.The angled teeth are a major improvement. Lessons the flex, it cams over and bites in a lot better. I would almost even recommend breaking out the angle grinder…lol
With that said…. The first couple of batches were absolute crap. The holes were drilled up to 1/4” off and on an angle. They didn’t even fold properly. They were pretty bad. The newest version is the bomb.
