Has anyone ever tried one of these? I'm wondering if this is a good way to explore straight razor shaving. I've never used a straight and thought this might be worth a try. Thoughts?
yes it's pretty much the same as a Parker Shavette. It is what I used for my first shaves.
I actually jumped right to straights, didn't have too many bloodletting issues (though I'm still learning), and no serious issues at all. I ended up getting the Bluebeards Revenge shavette (exact same as the Dreadnaught, just the UK logo instead of the US one on it), and I actually had a really rough shave trying to use it compared to a standard straight razor. While others find them similar, and even some prefer the shavette, I've put my shavette into the "For display only" razor rack and will stick to standard straights.
That being said, you can't be sure you'll like one or the other till you eventually try both.
