The chisel on the ebay link looks a bit light, and you would need to cut a very short length of pipe(3/8") to use as a top ferrule on the wood handle, otherwise the handle will blow apart when you start with the mallet. This chisel will allow you to mortice down, and a new, stronger handle would be easy enough to make....
