Long time lurker first time posting. Well anyway a few years ago started wet shaving got a couple of straights from the barbershop then sent them out to have honed from this site. Proceeded to cut up my face pretty bad cause of my own stupidity and impatience. So I switched to safety razors. Well I broke my leg and have plenty of time to practice what I have for razors are an old Imperial safety 20507 and a Geo Wonstenholm and son pipe razor. I would like to buy a new razor that is better than what I have.I was looking at Dovo and Theirs issard. So my question is what is better in blade quality that what I have now? The confusing thing is when I look at what I own I see that restored they still sell for decent money used.
I was thinking of half hollow but a little confused on blade materials.

thanks for the help..
