I'll add my "how I discovered chaps" story. There were two incidents.
First, my son was felling a small sapling on one of my steep slopes. As he came through the trunk, the saw dropped and took a slice just above his kness, which he didn't realize was naturally in it's path due to the slope. But he didn't want to go to the hospital (surprisingly it didn't hurt or bleed that bad though it looked ghastly - about 4" long and clear though the skin), so we bandaged it and he worked on it the rest of the day -about 5 hrs. But when sister (an RN) saw it and told him to get his stoopid tailfeathers to the hospital. They said he got there just in time, much longer and they would have refused to treat it. But surprisingly it really was "only a flesh wound"; a few stiches and he was good as new.
Now his dad is much smarter, and I was also aware of the previous incident. So I set out one day to lop some wild grapevine further along the same slope. My DW had made me agree not to go out sawing when no one else was home, but when I found some vines that far exceeded the lopper's capacity, I thought, well, I have my cell and I just have a couple of these things to get through, and I'll move carefully... Next thing I know I'm looking at a "smile" in my leg that was almost exactly the same as my son's, in the same place on the same knee.
I sat down, called him to come and get me, and had 21 stiches. Again, amazingly it was only a flesh wound. Very, VERY fortunately in neither case did we cut though anything but skin, but both times it went all the way though the skin - lots of hamburger and you could see the muscle sheath. But again it hardly hurt or bled - I walked back to the house, about 100 yds, and put the saw and tools away and was sitting there waiting for him when he came.
Now I had a $50 ER copay - and the stupid chaps only cost $44.95 about 2 years ago (Husquvarna). You talk about dumber than a sack full of hammers! It could have been so much worse, as I have read here!
All I can say is BUY THE CHAPS, chap! And my truly deep sympathies to those who didn't fare as well as my son & I.
