I've started using a shaving soap rather than the canned goo, it's the Wilkinson Sword blue bowl one (yes I have read the 'urinal puck scent' thread, but it's all that I can find at the moment!), and I am finding that the razor wants to move in a slightly jerky rather than smooth manner. The best description I can think of is it jumps or skips.

Is this caused by the soap or is it an angle thing?

I do use a little pre-shave oil, but only the smallest amount needed to cover my face - could it be this?

I'm still getting a comfortable shave, fairly close, but obviously I'm worried that it's going to 'jump' at the wrong moment and I'll cut off an earlobe!

Thanks in advance,
Paddy
