Gentlemen, I would appreciate some opinions on this safety razor.

Before I test it on my delicate skin I was wondering if I should sand down the underside of the head plate or leave it alone. Hopefully you can see in the pictures that there is a slight bend in the edge of the blade due to the dimples/dents on each corner of the top piece. Does anyone else have a new standard that looks the same? Also, it has that common crack in the handle near the top, it still fits tight but I was wondering what methods are out there to fix it permanently (solder, glue, jbweld, bubblegum)
