Sly gal here.
Just wanted to give a huge shout-out to the Remington HC4250 Shortcut Pro Self-Haircut Kit. I love this baby! I used the Wahl balding clippers before, but they were just too aggressive and I was kinda scared of them...and they were heavy to hold for that long. So I got the Remington HC4250 and it's battery-operated (Lithium-ion) and gives me multiple shaves per charge.
I love it because it's got a curved blade!
I haven't been worried about cutting myself once! I rinse it very well under a stream of water and the blades clean out without rusting or needing to be re-aligned (there's actually no way that I can tell for the blades to not be aligned).
While it's geared towards regular trims using guards for a variety of lengths, I use it solely for quick down-to-stubble sessions or for cutting things down enough so I can use my razor if it's been a while since I've last razor shaved.
It's so quick, easy to maneuver, with a great feel in the hand and lots of power to get through multiple sessions without needing to recharge. What's not to love?!
