Been using a Schick injector/Braun electric combo for...well...a long time.
I have an old straight razor but am afraid to use it.
Used disposable razors twice and will never use them again. Never used cartridges.Bill Cosby
Zip zop and my face is cut to shreds.
I have a '66 vintage Gillette slim DE. Nice razor but could never get used to the 3" handle and heavy head. Injector blades are getting hard to find, so I'm trying DEs again. Picked up an Merkur 25c open tooth razor and a 100 Red Personna blades. Total was about $52 and that's about $0.20 a double edge blade. This combo works nice for me. As well or better than what I'm used to. Got a '72 vintage Gillette 4" handle adjustable on the way.
I'm of the opinion that face prep is key to a good shave. Warm towels, warm water, pre shave oil...what ever it takes to "soften" the beard. Never owned a styptic pen or alum block.
Below is my current set-up.
