It is a feature that saves your fingers and a crippling disability, and while a sound attitude to safety should always be promoted,
accidents do happen , which is why we call them Accidents.
Statistics come from somewhere and even in the professional world of sound attitudes they can happen also. It's just one of those things.
Every year there are X amount of accidents, none of which were caused deliberately, and a range of factors were in play for this to happen
In our world, mainly working by ourselves, we should have a greater ability to concentrate on the job at hand, with none of the distractions you'll find in a big workshop, like other noises, people talking or talking to you. machine noise, that fav song on the radio, a sudden noise like someone dropping something etc etc probably a great number of things that can distract you from the job at hand.
While in the meat trade I sure didn't set out to cut or stab myself, but Ive 2 stabs to the leg and a range of hand scars
In the trade we have chainmail, and all of my little accidents came about from not wearing it, though in my latter days I started wearing a mail glove and not only felt safer, but i prevented accidental contact with my blade, which actually happens all the ttime as you are in many cased working with your free hand 1/4" from the blade tip in deep boning out of carcasses, pulling the muscle back to access the bone etc.
But accidents as we know do happen, and a device, any device that prevents such a serious injury is a worthy addition to any workshop be that professional or amateur.
Working with a saw bench,or whatever, a serious accident while working alone is probably the greatest risk to life. At least we can remove one danger from that equation.
Sorry I have to say this. But if you are the type that believes that an attitude to safety relies purely on that alone, then you are being very foolish.
