Thread: Frameback Inquiry

Hello,
I apologize in advance if this information is available in other parts of The Workshop or SRP forums. I've been using a straight razor for about three months now that was purchased off of SRP(my gratitude to you, Obie). After perusing the extensive database and libraries here I decided to try my hand at restoration for a hobby. I have a razor pictured here that was purchased in a lot(gratitude to you as well, rodb) that has, from what I was able to find, a frameback placed on the blade. I started using an 80 grit piece of wet/dry sandpaper to rid the blade of rust but the frameback seems to have rust where it meets the blade and goes underneath it as well. My question is, is there anyway to remove this frameback in order to properly sand away the rust? Thank you in advance for any and all help. I appreciate SRP and it's members to turning me onto the fascinating realm of straight razors.
