The Sandman is a wide handled Laser engraved Raking pick.

It works in a very similar action to the twin or triple peak rake. Its used in a fast skipping action under the pins but their is nothing wrong with using it as a rocker.

It design allows for it to be reversible. The Single Peak Side is designed for High/Low pinning.

These locks often also have two pins that are also close.

Example 2,7,9,4,3,2, The 2,7 being the high/low and the 4,3 being the similar
