Welcome to the forum 4everbald. Hang in there, your scalp will become accustomed to the blade. Big fan of HeadBlade here myself, and I just started using the ATX. Initially I wasn't crazy about it, but it takes a few uses to see how it works, and figure out it's nuances.
I will say one thing, it's damn tough to cut yourself with it. Very good tool, and will be a better choice for those new to headshaving.
