I just mailed off an interesting project: The biggest carcass splitter I've built to date. It was the widest and heaviest blade I've made (though not the longest), and I really want to make more. Probably will have one on my table at the Blade Show in June.

The blade is 18" long by 3 1/2" wide, with an overall length of 40 1/2".
Its size made it difficult to take a picture that really showed the size and proportions correctly, but I got a few, and shot a video comparing it with an antique carcass splitter I was given
