Just about every chainsaw carver that I know that has been injured has not been from a saw but the angle grinder, those lancelot attachments are the worst. The arbortec pro cutter works nice.
Also stay away from harbor freight sanding backup pad disk holders I had one self destruct and a chunk of the plastic lodged in the ceiling, very lucky I did not get hit even though I wear safety gear.
Went to their site and wrote a bad review twice they never put it up or acknowledged it.
Makita backup pads are robust.
