Recently I purchased a new Dovo str8 and have been using it to shave customers for about 2 months now. Last week I noticed hairline cracks in every direction on both the front and back of the blade. They were very shallow cracks resembling a spyder web and seemed to be on the finish of the blade.

I stopped using it and contacted the retail seller who said they would talk to the manufacturer. They called back a couple days later and told me they were sending me out a new one and to return the one with the cracks. When asked what caused the cracks they didn't really know and said they never heard of this before.

In 20+ years of using str8s I have never seen this before. I never dropped them or left them in water or subjected them to extreme heat or cold. I just used them as I regularly use all my str8s.

Does anyone know what could have caused this?

Thanks
