Just to maybe better explain myself, not that I'm expecting to change any minds...
When I was trying to be better about the situation the other day, it was probably one of the greater scenarios of worst chap situation (heavy and wet) mixed with low risk cutting (there is certainly a spectrum, e.g., logs on the ground versus hung up, wind thrown trees).
I know I have fallen a lot more wearing chaps wading through brush, nearly fallen while walking on logs, getting snagged.
I think that there is a balancing point with PPE. Chaps and a cutting jacket in a tree on a hot day or add rain gear on a cold and wet day, you would have less chainsaw cuts, but probably more injuries from falls, gaffs, dehydration, dropping stuff on groundies. There is no free lunch. That's all.
Stig, my impression is that with your martial arts training, mixed with logging/ tree experience, you're a pretty precise cutter. Your first accident sounded like it might have been a while ago, pre throttle interlock and chain brake, maybe. Hand on the trigger maybe. Combo of problems, somewhat made "moot" for lack of the right word, by technology.
The cut while climbing was a bit of a "oh shit, this is someone I know to be solid, but shit happened to him, so, listen up, it could happen to me. The magic wears off."
Burnham, obviously, you have your own credentials to stand on.
Honestly, part of it is "bulletproof-ness" from working at State Parks where the "objective danger" (unavoidable danger) was so high, regardless of what we did to mitigate. We didn't have a blaster. Getting speared by big limbs coming down from 100' isn't helped by chaps. I would explain to people at State Parks that cutting myself with huge chainsaw (by that I mean 880 with a 60" bar max, or a 660 with a 36" bar, so frequently) ranked relatively low compared to being killed by the other factors in what we did. The guy in my position previously was LifeFlight'ed out. Obviously, chainsaws are potentially dangerous, but felling bad to terrible hazard trees day in and day out made me feel that I could control far more of the danger of that aspect than the others.
My closest calls to serious injury doing residential work was from groundies F'ing up. A face shield saved me from getting blasted in the face with chips when the groundie moved the chute, without training, and without reason, then didn't clamp the chute he shouldn't have touched, allowing the force of big top shoved in the chipper to suddenly spin the chute to where I was standing. The other time was not PPE, but dumb luck.
I guess similarly, my concern about cutting my leg is much outweighed by cutting my arm and bleeding out in a tree, or getting crushed by something. Do I consider a cutting jacket for climbing or kevlar arm sleeves, yes.
I wonder, amongst climbers, how many have cut themselves, or know of someone personally who have cut themselves on their upper body, but don't wear upper body protection.
Getting ideas out on the page sometimes helps me work things out in my head, or get good ideas, like Justin with suspenders and chaps.
As a side note, when I'm questioning people why they do things a certain way that is counter-intuitive to me, it might come off as challenging, but really its information seeking.
