Most of the tools I have, I'm pretty confident using it. My first worm drive Skil circular saw had so much power as it would kick as soon as the trigger is pulled and would run away if both hands were not holding on to the saw, especially cutting up the floor. Pretty lucky with the tablesaw, couple of kickbacks was all and one loose carbide tip fling across the room at lightning speed. Drill press bit bind on a workpiece and almost took my hand off. Than came the chainsaw on the last cut on a 50 foot tree where it lean backward and bind the chain. The saw was useless at that point and I had no idea where that tree was going to land . Up to that point my most intimidating operation was ripping on a radial arm saw when the tablesaw was out of commission. Now the number spot, although not woodworking, is the handheld 14" gas saw with a composite cutting blade for steel. Couple of those blades blew up on me cutting at full throttle - just like a bomb went off. With about 5 hp at 4,000 rpm in your hands, you really have to think before hand how the cut is to be made and try to anticipate at what point the blade is going to bind or the work is going to shift and avoid the line of sight from the rotating blade or chain.
