I thought I was old school for still using power tools with an extension cord.
I still use non-power hand tools, too, just maybe not to the extent you do. I commonly use handsaws, coping saws, keyhole saws, miter saws, etc. rather than the equivalent power tool---particularly for a small job. I've probably used a small, sharp bow saw for hundreds of jobs where another person would probably use (misguidedly, in my estimation) a chain saw. It's easy to take up a tree or ladder with me, can almost always be used with one hand, starts every time, doesn't kick back, and it's wonderfully quiet. I still nail things together when that's faster than using a nailer, and sometimes when it isn't. However, I feel that the knowledge of how to use those kinds of tools is going to die with us.
