Wheel not stainless steel?
The unit is advertised as stainless steel, which I am sure the handle is.  But the wheel itself seems to be plastic, although I am not positive.  In any case, it is not very sharp.  I have a 3 headed wheel and those wheels are VERY sharp and have a different appearance. So it depends upon what you expect - a wheel that you can apply pressure and not have any fear of penetration (this one) or one that is very sharp and gives a very erotic feeling with proper care (the 3 headed one).
