I found this at a scrapyard. Actually it isn't a cleaver at all. It is a Foster Bros beef splitter. Before bandsaws were used in slaughter houses, these were used to convert a steer carcass into two sides of beef.

When you're holding an eight pound blade with a sixteen inch hanlde you know you can chop some meat.
I will be putting a new handle on it but it's not going to be what you would think. Of course I'll post pictures when it's finished.
