Garland Manufacturing has been making hammers and mallets in Saco, Maine since 1885. Their signature split-head hammer is the timber framer's mallet of choice, and the design behind it is genuinely clever: when a face wears out, you swap it instead of buying a new mallet.
Rawhide for chisel work, urethane for tougher driving, Gar-Dur for the hardest hits, plastic and elastomer for everything in between. It's a tool built around the assumption that you're going to use it hard, for a long time, and that's exactly what we do with ours. Maine-made, built to last, and one of our favorite local brands to carry.
