I was skeptical about buying a Dead On Hammer. How can you improve a tool that's always been there? Well he's dead. It has a big sweet spot and reduces fatigue by reducing vibration. I bought my wife a hammer - she's a real cowherd - and we fiddled with our fences. Well, anyone who spends hours hammering heavy staples and nails into fence posts gets tired. The Dead On Hammer makes the job easier. I want to buy me now.
