I did not plan to make this video. I was not even planning on taking them apart at all! It looks like it was good that due to a request from the comments section I did. There were some interesting findings. This is not a normal review type video. It is just disassembly of a tool or tools. No proper commentary, just pointer so you can have a look and make up your own mind. I hope it is helpful. These two tools had never been opened by me prior to this. Even so I have to say the screws on the C3 looked like they had been on and off a couple of times and I do not know why. Only I have had access to it since I got it!
