I 've felt that way myself.,, next time save the head for me and I will modify it for you, for free. You pay shipping but you might get a machined head
Should look like this, and grab what ever blade is giving you a problem, or ones that seems to shave bad
Place the blade on it. No need to fiddle around anymore. It should be perfect on each side with equal exposure.
Should be perfect. Straws are usually free, and you can make a lot of shims out of one straw . Do it right, it will last awhile. We have all bought a cheaper razor for some reason. That reason does not matter, If this solves the blade issue, great, if you are laughing , great, and if you can shave with it instead of buying a expensive one if you don't have the loot, or may go back to cartridges. No harm, no foul. It is a razor your pulling down your face with. All, in all, I hope it helps you, made you smile, and not run out and buy a new razor.
