Estwing Rock Picks are the #1 choice of geologist and palaeontologists worldwide. These American made striking tools are fully forged in one piece making them the strongest, longest lasting geological tools available. The chisel end is used to crack open rocks, and the square face used as a hammer to drive chisels. The 'Big Blue' version has a larger face than standard, allowing for higher impact. This rock pick features Estwing's patented Shock Reduction Grip which reduces impact vibration by over 70%. It is moulded and bonded directly to the tools steel core, meaning it will never slip, even under the harshest conditions.
