Ouch, that looks nasty!
If you were to use a normal razor then you wouldn't get nasty cuts like that! That eyebrow razor looks more like a steak knife "shudders".
Good luck with the the clippers tough, I hope they give you the desired result. If not give a normal razor a go, I haven't heard any thing about getting permanent hair loss from head shaving... most guys that are bald by choice can still grow their hair back out if they want too, but most never will!
