used straight razorquestions help needed

[mustangguy]

Hello everyone! I'm relatively new to straight razor community and have a few questions about a used straight razor I recently bought. A little back story first, along time ago in a galaxy far away, I decided straight razor shaving was a venture I wanted to take. I started with going to a local barber shop to get a straight razor shave and loved it. Then moved to a Dovo Shavette to try a cheaper alternative in the beginning. I've used it a few times and have gotten ok... I can't say anywhere near good or great. With that being said I wanted to step into the big boy league and got a decent condition used straight razor . The scales have some damage and I'm not to worried with that. I am worried about a few rough areas on the edge and spine . Can they be cleaned up or did I just waste my money ... I'll post pics if I can if not I'll try to describe it . The pics are poor quality but the edge near the heel of the blade looks jagged unlike the toe which looks straight and sharp . The spine on the otherhand looks pitted and discolored. Is there any suggestions anyone can of to bring it back to life or should I chuck it and buy a cheap new one ? I keep hearing people save just get a used one and clean it up . But how used or worn is too much ? Thanks for reading
