Hello Johanka!
Of course you are correct! I know that you are the best knife sharpener in the Czech Republic and your grandfather is the second best. I should have known that someone as bright as you would invent a better edge sharpness tester than we did and costs less as well. Its also much more colorful and pleasing to the eye.
Your instrument demonstrates perfectly the principle of edge sharpness testing and our S=F/A equation. Of course your grandfather was very helpful with this equation as well. This equation applies not only to BESS Test Media but to many other medias as well. Your rubber bands are an excellent example. A new axe blade (often referred to as an "axe bit" here in the USA) will typically measure between 900 and 1400 on the BESS. It is a good example of how different tools are sharpened to different levels and according to the application they are intended for. It is difficult for me to say what measurement you will get when you test an axe with your instrument because I have no experience with rubber bands as a test medium. I would very much be interested in the reading you do get though.
Please don't put your instrument into production before you graduate from secondary school. I have a few more of my own instruments here that I would like to sell before you do. Please stay in touch. Your writings are always smart and interesting.
Mike
