Do you think I've destroyed the edge on my toe-knife or is it savable? - Divisions by zero

My toe-knife has seen quite a bit of abuse over the last year and I’ve noticed that the edge has gotten pretty beat up, small chips missing here and there and of course getting a little dull for toe work. It’s a pretty small knife, blade is made of HAP40 steel and I believe the edge is only 44mm long. Do you fellow toe-knife enthusiasts believe it can be saved? If so there is a knife shop nearby I might bring it to as it is truly one of my most functional use anywhere toe-knives.
