The folks at Wilton have went and made a good looking, and "unbreakable" sledge hammer. They even made it in a bunch of different sizes so you can pick the right hammer for the job. The Wilton Unbreakable Sledge Hammers come in the following sizes; 2.5lb, 4lb, 6lb, 10lb, and 20lb.
The core of the hammer is solid steel, the head is a high visibility green/yellow color and is drop forged 46 HRC steel, the head is held on with a safety plate to prevent it from flying off, the neck has an anti-vibration bit, and the grip is a non-slip vulcanized rubber.
"At Wilton, we are on a never-ending journey to create the highest quality, most indestructible tools on the market. On this journey we’ve managed to design and file patents for the world’s most durable sledge hammer with Unbreakable Technology, revolutionary design, and engineered no-slip rubber grip. With the Wilton BASH backed by our $1,000 Guarantee, we put our money where our mouth is."
I never thought I would be watching a hammer video, but it is a decent advertisement and I suddenly want a new sledge hammer.
