I've started to think about trying an Open Comb. Looking at cadets for the price. What are your suggestions in the sub 30 dollar range? Vintage or new are both acceptable.
Yes.
Vintage wise, I think you should check out a Gillette NEW. They are relatively common and will be a good starting point.
Probably my favorite modern production open comb razor is the Fatip, which is a bit more on the aggressive side.
there are quite a few to choose from going from mild to off the chart blade on a stick.
What are you looking for? Something with more blade exposure? Something that looks cool?
An idea of what you want to end up with as far as the type of shave would be helpful to get meaningful recommendations.
Even saying something like "I use this razor but want something that is more like that" would be helpful so that we to know what to recommend to you otherwise you get more "Gee I have this razor" or "Gee I like that razor" type of answers which are not going to help you at all.
