I started with a billet of 4140 measuring 1.5" W x 3/4". My source for 4140 is McMaster-Carr.com. They are located in Robbinsville, NJ. Great company with fast shipping and excellent customer services. I will follow up with the overall dimensions of the axe, and some other pictures of the top and bottom. Thanks for the compliments and interest. I have had several orders for this style axe. It's just a nice useable tool.
