Okay, so I bought a razor to pracite sharpening with... It's a Harrison Bros and Howson (I've never heard of the company before, but it was cheap and on further inspection someone had put it in a H Boker box for some reason. :P). Now on to my question!

There seems to be a slight curve to the blade, what you might call a smile. It's somewhere around a 16th of an inch high in the center, maybe a touch less. I was wondering how big of an issue this is?

Also, if I wanted to straighten it back out, could I hone just the center for a while until I wear the high point down?
