My dad had the head of an old mattock that has been in our family for a while and asked me to find a replacement handle. The mattock eye was smaller than the others I own so I had trouble finding a handle that provided the eye dimensions that the handle would fit. I found the beaver-tooth website and it gave all of the details I needed to know the handle was correct for the size eye on my mattock. After some sanding and fitting to match the shape of the inside of the eye, the mattock looks great. Really great piece of wood.
