Does anyone have any ideas why a particular razor of mine has a tendency to cause irritation (specifically on my neck)?? I stopped shaving ATG with this razor. Even so, with a 2 pass WTG shave, I still have this problem...

None of my other razors will regularly do so.
The razor passes the general sharpness tests. Shaves very well.
Ive checked to make sure the razor is level.
No visible chips/nicks.
No rust or debris on the razor.

Should I clean it with something in particular?


Thanks for the input.
