This kitchen knife is toast. It's not coming back to anything resembling a working knife.
Replacing it would be cheapest, but the visible damage is not deep. It doesn’t have any severe chips and doesn’t appear badly bent. The frown at the heel is typical, usually seen on full bolstered knives. That needs to come down and then it needs to be reprofiled to establish a fresh, straight edge. After that, sharpened as usual.
I could have it back to working knife inside maybe fifteen minutes with a brick, a good slow belt sander, and paper wheels. With a brick alone, a good coarse stone, and some elbow grease, maybe an hour.
If this knife is toast, it’s because of a lack of knowledge, experience, equipment, or willingness to put in the work.
