The two I have are 18" long, straight handled, rip clawed, waffle faced "War Clubs" as most of my carpenter work was building concrete forms.
Missed once with an eastwing wannabe…..hit right at the base of the ring and pinky fingers…..both are still numb, ten years later. Even made a dent in the hand. The long handle came inhandy went stripping forms, too. Our's used "Dogs & Pins" to hold them together. We'd set 2×4 bases on the footers, and nail the forms down to the 2xs. half the time, went in a rush, we'd nail right through the sleepers into the dayold concrete footer. Sometimes, we'd drill a hole, add a duplex nail and a chunk of form wire, and drive that home.
Two hammer heads, and about four handles in six years…..Vaughn and Craftsman.
Could NOT hold onto a blue handled hammer…..way too skinny for my hands. Hammer would go flying out on the backswing…..
Most of the form work had to be done so we could tear it apart easy after the pour. And fast. Usually 75-100 feet of wall placed everyday, 5-6 days a week. Form both the inside and outside, and tie all the rebar each morning, place the 'crete by lunch. Start the strip before quitting time, rubber float the "show" side. Oil and place form to be ready for the next day…...go to the local drive-thru, pick up the cold ones for the ride home. Just gotta love the smell of form oil in the morning…..(yuck)smells like MONEY!
