Recently, I gave the Headblade ATX a 2 week trial run. First time using any Headblade razor. I like how it looks, and the fluid motion of shaving with it, but it doesn't seem to shave close at all. I have to go over random spots several times to achieve smoothness. Now, this could be because I wasn't holding it correctly, or maybe the Headblade brand 4 blade cartridge doesn't provide that close of a shave... Or a bit of both. The Headblade just couldn't catch on with me... Oh well. 'Least I can say I tried it.
I haven't tried it but to be honest I'm not getting the whole thing, which is why I haven't. I've seen the videos of how it works and the tutorials and I see no difference between it and how I shave with any cart. I use a Fusion by the way and a 4 pack of carts lasts me 4 months. My shaves are quick, clean and close.
But I shave the same way as I've seen the Headblade in action, and always have. I start at the front of my head and take one long pass all the way to the back. Top and sides done, I move to the back of my head starting at my neck and one pass to the top of the back of my head. I touch up around my ears (and a dent I have on my crown) and I'm done. BBS with one pass (ATG). I very rarely have to touch up unless my cart is nearing its end. So for this I don't see the difference other than the shape of the razor.
I like having the razor in my fingertips because fingers have dexterity and I feel in control and can maneuver with precision. I don't see the same control or maneuverability by palming it or wearing it like a ring. I've choked up on my razor in the past (the fusion has a sort of finger post behind the head) and used it more flat like a headblade but don't feel the "touch" I have with it in my fingers. But the shave strokes are the same so I'm not getting the whole idea behind the Headblade. Difference? Maybe I'm just missing something

In the videos the shave/passes/strokes looks the same as how I shave. The headblade just happens to look cooler

I've tried many different cartridges and the Fusion really works for me. Of course what works for one doesn't work for the next guy.
