I've been using a straight razor for about 5 years now, and highly recommend the switch with the same caveats others have mentioned. It does take a bit longer, it takes practice and confidence building to learn to use really well, I'm one of those people who's neck hair goes in all kinds of crazy directions and I'm still working on getting a closer shave there.
For me I would get a decent amount of razor burn and agitation from standard cartridges, the straight razor really improved that for me; I get ZERO of that stuff now, and I find the shave also lasts much longer. I currently maintain a beard on my face but not my neck, so I'm not doing a ton of shaving area and it takes about half an hour with the whole routine. Which I also find to be meditative and centering, like pipe smoking!
+1 for youtube and badger and blade those were both really helpful to me when I was starting out, and continuing to learn.
I'll also say that if you don't want to jump into sharpening it yourself you should look for a local knife sharpening business! The good ones will also know what to do with a straight razor and shouldn't cost you a ton. I used to cook professionally and have several Japanese wet stones for sharpening my chef's knives. I however don't trust my self to sharpen my razor, its a different angle and process from knives and I'm certainly less worried if I make a mistake on a knife I'm cutting up chicken with VS something that has to NOT cut or rough ME up. I called around to find a sharpener that had experience with straight razors and I use them now, it costs about 40 bucks and with the amount I'm shaving I've only had to have it sharpened once a year.
I'm also using a Japanese Kamisori Style razor that my wife and some close friends got me for a few years back from
Handmade Straight Razors and Fine Shave Goods | ShaveSmith - https://shavesmith.com/ I love it and wont be going back to the other style.
All that being said there are a ton of options for soaps and pre/post shave products out there online that you can experiment and really find what you like and works for you. Its been and continues to be a fun adventure for me so welcome!
