I am relatively new to sheaffers and pen restoration in general. I have restored my friend's Sheaffer Imperial, but somehow when I got one for myself, the screw was either sealed in and rusted or just rusted in, but i could not even get a grip on it with a screwdriver as the screw had corroded and was stripped. I have limited tools and I don't plan on buying any online. I have also searched online but the suggestions require tools I don't posses or are too risky and I don't want to try. Any suggestions? Sorry I could not get a clear photo of the screw.
