Something to add is that the zoom amount (per scroll wheel rotation) varies based on the distance you are from the object to which you are zooming. I'm not sure what the exact algorithm is, but it appears that a rotation cuts the distance to the object in half with each rotation. So with each turn of the wheel, the amount of zoom decreases allowing you to have finer and finer control over the zoom amount as you get closer and closer to the object of interest.

This can be frustrating when you zoom inside a solid object, as the next object of interest is the opposite wall of that object. So you might need to rotate the wheel many times to traverse the 3/4" to the opposite side of a piece of wood (if you find yourself in a termite's perspective). This is when zoom-extents is most handy - to get you back outside of something you have drilled into accidentally.

Well for the specific example, I'd loan him something sharp but cheaper of the needed size if I had it, or I would loan him the golden chisel if not. This is assuming the requester is a friend.

I would never embarrass a friend by rejecting a request like that, nor would I let his uninformed abuse of it turn into a an embarrassing situation for him. I can buy new tools but friends are priceless. I tend to loan as well as borrow with my friends when a specialized tool is sought, and they would all do the same for me.
