Right now I have a beard. But when I don't, I shave daily. I use a Merkur double edge safety razor like this:
There's 3 main ways of shaving:
2. disposable blades
3. old school - straight blade or safety razor
I've tried all 3, but because of my thick beard only the safety razor works for me. It has the nice side benefit of being inexpensive. The last time I bought blades, they were $20 for 100. I use 1 blade per week, so essentially a 2 year supply @ 20 cents/week. The razor itself is an initial investment, but long term is far less expensive than disposables. I used to use a shaving brush to apply soap from a mug (old school style), but have settled on using the lotion style from a can.
What do you use & why?
I tend to take things to extremes...
Safety razor - shave three times (down, sideways then upstrokes) fresh foam for each shave - for that smooth feeling.
I only use a badger hair brush and Proraso Pre-shave, shave soap and after shave.
Finish off with a final shave using a wet/dry Norelco electric shaver (with more foam) for that baby smooth skin.
All up - 15 minutes effort.
My wife loves it.
