This is the finest folding pick set on the market, period! The body is machined from solid aluminum billet with the precision of a Swiss watchmaker. The locking lever needs only to be pushed up 90 degrees to allow the 8 picks to move freely. When tightened the locking lever positively locks all picks. The Jack Knife comes set up with the following picks: #2, 5, 8, 11, 12, 13, 15, 17 and one Bullnose tension tool. Removal of the tension tool from its storage slot is accomplished with a simple push in the thumb slot. The tool will snap out into your hand, no broken thumbnails! The 8 picks can be easily removed and changed and requires no tools. Upon request we can modify the"Jack Knife" lock picks to better fit your needs.
