Review on MERKUR Slant MK 37C Double Safety by Jocelyn Hernandez

Based on everyone else's feedback I expect this razor to work very well. When comparing my Merkur HD 34C and 37C, however, the difference in quality becomes clear. There has been some negative feedback on the 37C for thread stripping and I can see why. I thought the stripped threads were the result of over tightening the head or not lubricating the threads to prevent corrosion. Now I see that the 37C thread is very poorly finished and doesn't go around the full perimeter of the post. 34C is the left razor and 37C is the right razor in the images. This is a weak point and can lead to premature shaver failure. If I had known that about the threads I might have bought a different 34C for my son instead since he shaves now. I'm really surprised by this, especially considering the 37C is more expensive. I'll use it and tighten just enough to hold the blade.
