Look man, you can milk a goat and ride a moped cross country, but if you want a milkshake and a Harley, both the previous options will leave you wanting. Sure, they'll work, but why not just do it right the first time?
Learn to shave with a straight that has been honed properly. Then buy this set up. Hone a razor with it. Report back to us how it shaves. If it works well, and the edges are as sharp, smooth, and long lasting as a traditional honing I'll bet you everyone will cede the point. But why start behind the ball? Just get the stuff you need from the beginning.
Sharpening knives is not honing razors. You can make a knife "razor sharp" on 600 grit sandpaper. That doesn't mean it will shave smoothly. Lots of knife guys have issues wrapping their minds around that.
