I learned to shave with a DE razor after Gillette decided that all men need to atone for rape. Meanwhile Gillette is the one raping men via their massively overpriced cartridge blades.
I found a hobbyist who was selling starter kits which were basically vintage Gillette razors, a synthetic brush, palmolive shaving soap, an assortment of blades, and some instructions. All of this at an absurdly cheap price. I wound up getting a near mint condition Gillette Superspeed from the 60's. Wet shaving had a big boom thereafter and the prices of vintage Gillette exploded. Bet he regretted giving away vintage shaving gear for next to nothing.
There is an amount of autism in wet shaving. Some of it is some sort of displaced form of trichotillomania combined with a collectors mentality. They'll insist your technique of lathering is incorrect and can't possibly work. Ignore them. Shaving is one of those things is if it works for you, it works for you. My one and only brush and one and only razor works just fine. Some people literally have 100's of different soaps and dozens of brushes. Others collect the lastest custom CNC produced razors in various exotic alloys. Then there are the people who have a collection of straight razors and strops.
Don't overlook shave cream. I like the palmolive shave cream imported from the UK. Wet the shave brush with hot water and wring with your fingers. Take your shave bowl, rinse with hot water and drain leaving a fine layer of water on the shave bowl. Apply bead of shaving cream to tip of shaving brush in similar size to what you'd put on a toothbrush. Whip shaving cream into lather in the shaving bowl. Apply to face.
The performance of the soaps/creams vs the quality of the blades interact. Some blades with Van Der Hagen shave soap will rip my face up, but be gentle with the Palmolive.
When you combine the razor blade angle of each razor design, blades, shave soaps, and your unique hair and skin makeup the number of combinations is endless and what works and what doesn't is highly individualistic. Wet shaving is like using linux.
The cost of DE blades is ever so cheap. When Russia invaded the Ukraine, I bought many hundreds of the made in Russia Gillette blades. We are talking a nickle a blade. A blade will nearly last me a week. I got enough blades in my stockpile to likely last the rest of my life. If the shit hits the fan, common bath soap will also work.
DE shaving is so cheap, I really believe that it is an actual conspiracy to suppress the older tech as it clearly wouldn't be profitable. Should DE shaving actually become mainstream again, I think the CPSC via lobbying from Gillette will suddenly declare that the blades are a danger to children, and the manufacture, sale and importation of non cartridge razor blades for shaving will be prohibited by federal law.
