I bought a bunch of new Nicholson files to replace my aging set which has faithfully served me for the last 5 years. I had "acquired" the files after "borrowing" a bag of them when the scrappy I worked for went into liquidation so I got several of each type, enough to last me until now. However the new files I purchased are showing signs of wear and tear after a mere two days of use, the double cut bastard is already marred with shiny teeth, particularly, and most annoyingly, at the corners. This trend seems to be a theme among the other files I got as well, they are all just way too soft. Has anyone else had this problem with Nicholson recently or did I just get extremely unlucky?
