hello everyone hope you guys are having a nice day.
i am recently in the process of becoming overly concerned about the flatness of my stones and so i have purchased a bevelled straight edge, which looks like the picture.
now before you say this level of flatness is not important i am aware of the fact, but for reasons beyond me it is important for me to get the stone as flat as i can.
so now to my question, i have been reading and it seems the best method to use the straight edge is to place it on top of the surface and shine a light from the other side of it and if light is seen then the surface is not flat.
my problem is that because of the knife like shape of my straight edge light is shining no matter what surface i am testing(my DMT, plates of glass etc.) and so this method of evaluation doesent seem to work as i am unable to differentiate between flat and not flat .
anyone familiar with these have another solution or tip for the proper usage of the straight edge ?
thank you for any input .
