That’s something I notice often when people are sharpening different objects and then calling them "razor sharp", while there is a difference between "sharp object" and "razor sharp". But with a bit of reading on the straight razor section, you can understand what is the delta and how you can get to real "razor sharp".Yes i have tried to sharpen it already up to 10k grit and completely reground the bevel but i still lack the experience to perfect the final edge.
Previously i thought i was able to sharpen something razor sharp no problem but then i encountered DE blades and omg was i wrong.
