I like to make push sticks that not only do their job but also feel comfortable to the hand. This takes a little time and then, sooner or later, you cut the step or notch away and have to make a new one. My new model push stick has a short piece of hardwood dowel with a flattened aspect on its forward surface, as shown below. When it wears down, I just drill out the old dowel and replace it with a new one – a couple of minutes’ work.
