A friend of my father gave me this straight... I've been using safety razors for years, but this is my first straight, so I'm hoping you guys can tell me a little about it and whether it's worth trying to clean/sharpen up. As you see, the handle has some sort of bird engraved on it, don't know what the handle is made of? The blade says T MAHFOUZ and has some scroll-work on each side of that word/s. Close to the handle it says T. MAHFOUZ and N Y underneath that. On the other side of the blade, however, close to the handle it says "Germany 92". The whole thing looks like it needs to be cleaned and shined, but I don't know how to do so without causing some problems with it potentially, so again, I'm asking for the help of the group. Thanks
