I have never nicked my skin with a chainsaw.
I have had a few minor scratches with a handsaw.
A co-worker has been nicking himself with handsaw almost ever week lately, he says, "maybe you should take it away from me."
I said, you gotta work on thinking about the plain that the saw is working in. Picture that saw continueing in the direction you are using it.
Is any body part (or anything else important) in the direction the blade is going?
always treat it like the blade is going to continue in it's path. If it would contact something important, change things so it can not.
Sometimes I work with a handsaw or hatchet (on the ground, cutting a girdling root) with my left hand behind my back.
It made me wonder what caused me to have proper technique.
I was thinking first it was because I used to play with butterfly knives as a teenager.
then i thought of something.
When I was like 10 years old, I was trying to cut bailing twine with a dull pen knife, I folded the twine over the blade, held it tight and pulled the blade toward myself. Well, after a lot of force it cut the twine, but the blade continued and hit me in the eye. it cut a small sliver off my cornea. Wow, it was painful.
My eye luckily healed without any scar, with medicine and eyepatch.
But, maybe, because of my age at the time and the event, it helped me be more careful with cutting tools and their path of cutting.
