Where are these products manufactured?

Should I get my tools professionally sharpened?

While it may seem unnecessary to some, Diablo does recommend the use of authorized sharpening services to maintain "like new" tool performance. As these tools are precisely crafted to ensure maximum performance every time. Diablo requires "extremely tight tolerances" which may not be met by individuals lacking the necessary experience and tools.

While you are free to do as you please, please consider using an Authorized Sharpening Service Center.
