Hello everyone,

Last week my brand new Belgian Yellow Fine/Selected Grade Coticule arrived in my mail. She's a sexy hone I have to admit. My question is simple - How can you tell if a hone (brand new in this case) needs lapping? Judging by eyes only the surface is very smooth and straight imo at least. Are there ANY tests/techniques that can tell you if a hone's surface is perfectly flat? Something that doesn't involve high-tech tools preferably as I have no access to any of those tools. Thank you! Sorry for the newb question
