Kitchen appliances like toasters and blenders were better when they were entirely made of metal and wood. Woodworking tools were better. D-handles on shovels were better made of wood and metal. Car parts were better when they were all steel. Personal story: I owned a car with a hood supported by pneumatic struts. The ends of those struts were plastic. One end split and broke. I was told I couldn't get a fifty cent piece of plastic to replace the end, I had to buy the entire strut for a hundred dollars. Plastic dries out, it becomes brittle, and it cracks. That's just the reality of it. I had a photographic enlarger with plastic knobs. It sat in the closet for a few years. When I went to use it, the knobs broke into pieces. All the strength had gone out of the plastic. (Word to the wise, never buy something such as a photo tripod with plastic knobs to lock the legs into place. The plastic will fail, it's only a matter of time.) I hate plastic.
