This Double sided stick is a great add on to anyone who likes to spend their free time fishing on the water. The One side has groves to slide your hook down to sharpen the edge, The other side is flat to for any other hook or knife needs. The stick is only 5" when packed away and with a quarter turn, you can pull the diamond stick out and attach again with a quarter turn. The stick will then be just over 9in. Quite a comfortable length to carry and work with. This will be quite a nice add on to any pack, or tackle box for those who like to spend their time near water.
