Any way to save a new (NOS) razor that has a hairline crack in the blade at the edge? I got this razor in wonderful condition from an ebay purchase, and not for much money. Neither he, nor I looking at the pictures found that crack. When I got the razor and held it up in the light just right I saw the slight distortion along the blade edge. Magnification shows a hairline crack kind of in the shape of a ( but a little more curve at the top back toward the toe. It was an A. FIEST & Cie. Solingen Germany, model "Monterna" in very fancy italics on the Left tang, along with Fully Hollow Ground, under the name Monterna.
He felt bad about it, sent me another razor, a Geo. Wostenholm & Sons to replace it, so that was very decent of him. I told him this razor is basically new, with no hone marks at all, and does not look like it was ever honed or stropped. VERY thin blade that starts nearly all the way up the blade close to the spine, and highly polished, ALL of it. I think his Father, who passed away and left him the collection of over 100 razors, probably had it and never used it for this reason.
Is there a way to perhaps add super-glue to both sides, or J.B. Weld or some low temp 95C silver based solder (melts with a cigarette lighter) to the spot where the crack is and stabilize the crack?

This is a picture of the whole razor, but forgive the off hue. I used the wrong setting on my camera, and managed to fix it a bit with Photoshop.
