I recently tried my Dads Merkur HD whilst he tried my Gillete Slim. Whilst I have only good things to say about the quality of the shave with the HD, I did notice that there was a small dent in the metal on the head of the razor, and a bump underneath the head (not under the dent) which, well I'm not sure quite what it was. Could it be corrosion of the metal? Surely not as the razor isn't even a year old yet. Could it be a manufacturing problem? Has anyone else noticed any blemishes on their Merkurs? The Gillette Slim, despite being 14 years older than me, (I'm 30) has not got any dents whatsoever apart from a small tarnished area on the head. Is the metal in a Gillette somehow superior to that of a Merkur?
