High Reach 0.020 Thick with metal handle
Thinner picks are often needed for narrow keyways or high/low pin stacks.
They also work best with top of keyway tension.
These 0.020 picks allow for slightly more working room than a standard pick.
This extra room can allow for different angles of attack on the pins resulting in more picking possibilities.

Standard picks are 0.025 thick and their is nothing wrong with flexibility in a .015 pick.
Often you want that flex to help position the pick.
