I previously purchase a hardened steel file guide from an established supplier but when it came in I noticed that no matter how much I tried to align the 2x surfaces they wouldn't line up. With that said I had a friend from work grind the guide square. Sadly though we must have ground off the hardened material because my files are now removing material from the guide. 
With that said I am now back in the marker for a new file guide. :/ I have seen several variations out there with carbide guides guides on the market and any recommendations for a particular supplier would be greatly appreciated.
Regards.
