Fiberglass Sinking Hammer - 16 oz. Although not American made, this hammer has all the features you would expect from a Cooper tool. I've been a fan of Plumb's Perm-a-Bond handles for over 30 years (I own many of their axes, axes, sledgehammers and various types of hammers). If you've ever lost the head of a hammer or ax you're frustrated and afraid of hurting yourself or someone else if the head falls off. This is what you will come across when using the perm-a-bond tool. It's always ready when you need it. It feels good in your hand and thanks to the rubberized grip you can be sure that it won't slip out of your hand. The quality of fit and finish is such that this hammer would be a great buy even at a much higher price point.
