Produced from the highest quality Eklind Alloy Steel which is heat treated for maximum strength and finished to resist rust. Superior quality provides maximum torque and prevents rounding out of the key or hex socket. Combination sets are available in popular inch and metric sizes that are color coded for easy identification. RED for INCH, BLUE for METRIC, and GREEN for TORX. Designed with a ball profile on the long arm which provides 360 degrees of rotation at up to a 35 degree angle. The burr-free short arm allows user to apply maximum torque in required applications.

Unfortunately, the statement
Pros
A short, burr-free lever allows the user to apply maximum torque in the applications required.
