After having my blue DMT Diafold for quite a while now it seems it has worn out. It's so smooth, I can't even use it as a nail file anymore. Over the years I sharpened several stainless,A2 and Stellite blades with it. I tried not to apply too much pressure and used water as a lubricant as recommended by DMT.
My questions now, is that wear normal and how long do these hones usually last?
