I have been playing around with ideas for a small , little business to start when I retire . Not trying to make a fortune . just a little extra cash and something to do . One of the ideas involves knife sharpening . All my daughters have a drawer full of knifes that are dull as butter knifes and every where I go I see unbelivably dull knifes . WHAT IF---- I get me a little van , put a few simple tools in it and I go door to door , offering to expertly sharpen any knife or sizzor (spel?)you have ? Should I just advertise ? How much should I charge ? Do you think it would work ? I know that all of you have guys who understand knifes and don't have this problem but you are not the norm . Please..... don't just tell me I am crazy . Be gentle .
