Is this repairable/worth the effort?

I found this in a friends kitchen drawer and he gave it to me. It is an 8” chef knife. After looking at it appears that some mensa brain tried to unscrew a flat head screw with the blade! The crack is a hair over 2mm deep. It is located about 3.5” from the bolster.

Firstly, is it worth the effort? If so how would you attack it? I understand it would take some significant reprofiling (perhaps an excuse to buy a 1x30 belt sander?). I’ve never attempted anything like this.

Any insight/comments are appreciated.
