[The recent joint venture of Cooper Tools and Danaher Tool Group affords a broader line-up of leading hand and power tool brands.] Striking tools from Plumb®, a brand from APEX Tool Group, were first produced in a small Philadelphia blacksmith shop in 1856, and Plumb® has since risen to become the most popular brand of hammers and axes in the world. The Plumb® story has always been one of superior product quality and durability. Today that tradition continues with high quality Plumb® hammers, axes and hatchets.
