Please be advised that there has been a significant revision to the current ASTM A228 specification for Music Wire.

There is now a Type 1 and Type 2 designation. Type 1 is Direct Drawn, Type 2 is Patented.

Further, air patented rods (also referred to as Stelmer Patenting) does NOT qualify for Type 2 Patented per the new standard.

The term lead patented is not specifically used, allowing for equal or improved alternative methods, whereas, again, air patenting methods are NOT allowable for Type 2.
