For me, and keep in mind I only shave about twice a week and have a heavy, high carbon steel wire like red beard that would turn Gillet Mach 2's into a comb after 2 shaves, I hone every 4-5 shave, depending on the razor. The only factory razor I use is a Gold Dollar and while it works well after I re did the edge, I only get a couple shaves before I need to lightly hone. I have one I made from 1084 and 15&20 damascus and it's my favorite, get about 4-5 shaves before I give it a hone. The best one I have for edge holding is one I forged from 52100, upwards of 10 shaves before needing a hone, but it's the first razor I made and somewhat ungainly in design and shape, so I don't use it much. The Gold Dollar is very thin and would likely hold up better if I was using it every day or two. The one with the simple high carbon steel is my favorite mainly due to shape and how well it handles my heavy beard, but I'm planing on making another with a 52100 blade just to compare. The hone angle I believe is around 15 deg. From research I've basically come to a 1/4 to 1 ratio, if the blade is 1" wide, it should have about a 1/4" thick spine to give the correct hone angle and is working well so far.
As an aside, I haven't shaved with a conventional razor in going on two years now. It's a little more trouble, but I don't get razor bumps or irritation like I use to, and frankly after figuring out the basics have cut myself less than with conventional razors, especially the old safety razors.
