Thanks in advance.

Unless you are referring to a Pakistani razor it won't be steel quality that is the problem. What it usually is related to is the hardening process. The razor blanks are quenched after heating which warps most of them. They lay them on a leather pad and whack them with a dead blow hammer which restores their original shape - most of the time. Then they are tempered to remove stress. The ones that obviously don't look right are wastage; however sometimes they are flawed in a way that isn't even noticeable when the grinder does his thing. These get passed on to the customer. Quite unintentionally! Then when it is honed you will notice the flaw. If metal only comes off the tip and heal on one side and only off the middle of the blade on the other - it is slightly bent laterally. If metal comes off the front half on one side of the blade and off the heal half on the other side - the blade is slightly twisted.
