Here is a pair (right-handed & left-handed) shuttle. Ha,Ha....this is a little joke we play on the new recruits. We would ask them to get a left-handed wrench. Some of them get it, others would look for hours and ask around. That was from another life, long ago.
These traditional fish shuttles were made from black walnut. They measure 3" long and 1" across. They tat nicely!!
