There is such a small contact patch, that minimal force can exceed the yield point of steel. It is measured as lbf/in2
You need a piece of o-1 drill rod. Heat it and quench, then a little temper to keep it around Rockwell 52. Those other little plates are normally hardened and surface ground as well. Otherwise it won’t skate.
