I've had a few run-ins with axes. The first happened when I was ~20 years old. I was using a boys axe to bust up some pallets for firewood. I heated my home with pallets that year. I didn't hit myself with the axe but rather a piece of shattered wood flew up and hit me in the forehead. My girlfriend told a colorful story about 'hitting myself in the head with an axe'.
Maybe a decade ago I was falling small forest fire killed pines for a campfire up on Hart's Pass in the North Cascades of Washington. A glancing blow threw my boys axe (a different one) into my shin. Luckily it hit the heavy seam at the bottom of the double knee of my Carhartt trousers. After cutting through the trousers it cut my leg about 1-1/2" long x 3/8" deep. At camp I was able to close the wound with butterfly style bandaging so we didn't have to break camp to go get stitches. It took 2 months to heal and I still have a scar.
I few years ago I was cutting kindling to light my coal forge. I was working at my carving stump with my Stubai hewing hatchet. An errant blow opened a gash on a fingertip of my opposite hand. I went in and got that one stitched up.
I respect axes. I understand that a trip to the hospital is as close as a slight lapse of attention. It keeps me thoughtful of how I use them.
Keep 'em sharp!
