While I like the idea of the chainsaw blade for the grinder, I don't like the idea of leaking blood so much I have to quit work.
Well, if they build it, I can run it I guess.
For light occasional use I would consider a battery powered saw, not having to mix and carry gas is a primary reason, secondarily we have combustion engine shut down hours during fire season, I haven't checked, BUT my guess is you could still use the battery operated saw. 20+ years ago we would saw line all day long, but happy to say I haven't needed to do that in the last 20 years, if your need is for heavy saw work, then battery isn't going to cut it. I currently carry a battery operated string trimmer and hammer drill in the survey wagon, both have served me well.
