When you are starting out, nicks are to be expected, even with a traditional straight and starting out, you may most likely end up nicking yourself while you learn this new form of shaving, which is completely different to the old one where you put a 20 blade cartridge shaver to your face and it does all the work.

As for the angle and the touch it does matter. Having a correct angle means you are less likely to nick yourself, and a light touch helps when you don't get the right angle and nick yourself, it won't be too deep.

I occasionally shave with a disposable blade straight when I am in a hurry coz it saves time. Now that I am more experienced, I no longer nick myself.

Straight shaving takes time and patience.
that is true, but I don't experience these problems after the razor has been used a few times. I get a pretty darn close shave then, comparable to the mach 5. no hairs. And where I experience the problem is when i go for the second pass up and against the grain. if there is a better way, and it takes time for that, then I guess I will see. however like I said, when it has been used a few times I don't get this problem as much.. still a few nicks here and there but not like when it is new. i also wonder if people are as much of a stickler as me. does everyone go back against the grain? do others also try and make it so that they can't feel any stubble at all? if that is the case with most people, and I only have to keep getting better at it than i already am, then that is definitley heartening!
