Problems with a cleaver.

have a client wanting a western style cleaver.

Ive had 2 failures. First broke at the ricaaso. (Cold shut) the second developed a mystery crack during grinding. I'm worried I'm trying to move the metal too much. Or perhaps using the wrong metal. My starting piece is 4.5" x 2.5" x 0.75" of O1. The ending cshape is about 5.5" blade about 4.25" wide and a 5.5" tang that's tapered from 0.325 to about .18"
Can't seem to find an image hoster that works. Have a pic of the grain. It looks satin like as far as I can tell. No large grains. It is preheat-treatment tho too.
Anyone have any thoughts or suggestions. They would be greatly appreciated.

Thank you for your time

Chris

 
Sounds like forging too cold. Forge between 1700F and 1900F. Don't forge O-1 below 1600F, which is still a bright red.
