Thanked: 735I sent Dovo the pics of my blade and of my proceedure to establish that the blade was warped (precision granite plate certified to 2um flatness).
I also wanted to let you know the method I used to determine that the blades were warped, it may help when discussing issues with the manufacturing/QC department, as I know there can be many variables (a hone that is not lapped correctly, etc..). It only took me about 30 seconds to determine that razors 2& 3 were curved, as I knew what I was looking for at that point. The first razor I spent 30 minutes trying to hone before I finally took a look under the microscope and saw that there was something not right with the razor (I'm an engineer...)
I have a precision flat granite plate, certified flat to 2 microns accuracy (see attached pics), I mount a sheet of diamond lapping film (3um grit) to the granite plate. I put a line of marker pen down the edge of the razor and then give a few passes over the lapping film. In the third attached picture it can be clearly seen that material is being removed only at the toe and heel of the razor, the main portion of the blade is not making contact with the hone at all.
On the other side of the blade, the reverse is true: it makes contact only in the middle, and not at the ends. While contact only in the middle is usually indicative of a "smiling" razor, the fact that the other side of the razor makes contact only at the ends shows that it is curved lengthwise.
All three of the razors were curved exactly the same. The side of the blade without the gold wash & etching was the side that made contact only at toe & heel.
I would encourage your QC department to employ some sort of test such as this to determine blade flatness prior to shipment. The precision plate cost me $20, and the test only took me about 30 seconds to complete. The fact that the three razors all were curved in exactly the same manner would seem to also indicate a possible tooling error, or something that is causing repetitive defects, not just random errors.
My vendor was excellent at customer service. As I said, they tried three times to send me a replacement, and all of them were unaceptable. At that point between they and I , we were spending altogether too much $$$ on shipping alone and we decided to give up.
Having to ship it back and wait 6-9 months (as has been what is commonly occuring in direct to manufacturer returns on the forum) is completely unreasonable.
I don't really want Dovo to "do" anything for me at this point. I just want them to know that they have a problem with their product.
I'm not encouraging people to flame Dovo with angry emails, but to simply give them feedback, let them know there are issues with the razors that may be more common than they should be.
