I want to solicit some suggestions from you all on a small problem I'm having with my Against the Grain passes.

I do quit well on my neck, chin, and right side cheek. The problem occurs when I switch to my left hand to shave my left cheek. I seem to get a pulling feel when I try this and nowhere else. It is almost as if the razor is road-blocked and just wont pass over any hair. The strange thing is I work through it, re-later and go again and it's perfectly smooth. I also (as mentioned) have no problems with other areas on my face so I know for sure it isn't the blade dulling.

My best thought are my angle or I'm just not proficient with my left hand (are those the same thing?).
