9-in-1 Builder's Pen Multi-toolBuilders 9 in 1 Pen Multi Tool is a metal multi tool pen designed for quick fixes and measurements in everyday carry pocket or pack use. I was halfway across a desert trail when I felt the binoculars slip. A loose screw. Heat rising off the sand. No shade for miles. I pulled the Builders Pen from my pocket and tightened it with the precision bit tucked inside the barrel. Clean turn. Solid click. The view sharpened and I kept moving. Signed, Lucky Jack
