David, Yes, I understand. I just thought you meant the way the thread runs as I wrote. Some years ago I bought pins from US where the thread was cut after making them blue or nickel plated and they felt sharper than other pins. Logically it should be the best way to make tuning pins.

The idea is that the pin should set better. It is a strange feeling when tuning. Erwinspiano@aol.com skrev: <dl> <dd>  Hi David </dd><dd>  What you mean reverse torque pin ?
