Query: REVIEW FROM A PROFESSINAL BUILDER: IT'S WORTH IT

I bought this hammer after struggling with nasty tennis elbow for about four years. Bottom line, it's light, really light. You swing it faster with less effort, and it hits hard. Very well balanced, and swings great. Frame with it all day, and arm feels good. I do use it for an all around hammer as well, but it's a little too big for some stuff. If you have elbow problems, cough up the extra bucks for this hammer, it's cheaper than those cortazone shots
