I used this fellow and got great results:
Micro Precision Welding
51797 County Road 652 Mattawan, MI 49071
Phone: 269.668.2760 - Fax: 269.668.2760
He actually Laser welded it. The tang was repaired from the bottom so I didn't need to have it re-engraved. I have two pictures to attach if I can figure out how.
