When I bring up something that personal.... Yes, I do. Otherwise, its a waste of my breathe to talk about it.
I made that mistake once. I asked my wife who lit the fuse on her tampon. I didn't see her for 3 days.
After the third day I could see a little out of my left eye.
Shave every 3 days with a disposable and give her lots of kisses on days 2 & 3, when she complains tell her it irritates your face to much and the safety razor don't.
My wife wasn't 100% on board with my safety razor at first either. I simply started shaving with the DE. Once I had the technique down really good; I would sit next to her and give her a kiss, making sure she could feel how smooth the DE shaved. After no time at all she said "You can never go back to a normal razor." I agreed, but I've got a pretty long beard now. ; )
Safety blades- 10 for $1.70
Mach 5(?) blades 10 -$34.00
Forget about finding the "right" blade, they'll all shave well, just work on your technique and take your time. Shorter strokes and two directions....first with the grain, then against it after lathering up again.
While all DE blades will shave you I can definitely tell a difference in them. Derbys don't work for me at all but there are guys who swear by them. I've used every type of DE blade I could find and the Feather works best for me. Some guys say the Feather eats their face like a rabid badger. Your mileage may vary. Professional driver on closed course.
Definitely work on technique and don't rush. I normally do the first pass with the grain (mind that the grain may be different directions on different parts of your face). Second pass I do at a 90 degree angle to the first. So if you do N-S first do E-W second. Third pass (against the grain) I reserve for those "special" times when my face has a better than average chance of coming into extended contact w/Mrs. Danger.
I don't see how your wife, in any case, has anything to do with how you shave. Kindly let her know, that her opinions on your shaving, she is to keep to herself.
6 pages in, I'm surprised this hasn't been posted yet:
"Tell her to get her b*tch ass back in the kitchen and bake you a pie!"
This is going to sound a little flip, but if I were you, I'd tell her not to "worry her little head none", and make a joke out of it about "it's a man thing---you wouldn't understand". And I'd blow it off and keep right on shaving. I'd treat it the same way I would if she made a fuss about me using "dangerous" power tools, going hunting in the woods, climbing ladders that didn't look safe, or riding a motorcycle---a little risk is just part of the territory.
A. she's just worried about you cutting yourself (as any good wife would be)--but you're not putting her at risk or hurting your family;
B. you don't need her approval for this---it's a skill you want to develop, and the fact that it's important to you (for WHATEVER reason) doesn't have to make sense to her.
Don't worry about getting her on board with it. Buy some styptic pencils and learn to shave the way you want to...she'll get used to it.
How does she feel about minimizing her carbon footprint?
Disposable razors are terribly wasteful, not to mention expensive. Convince her, on an environmental basis, why a nice razor that can be used for generations is a MUCH smarter choice, long term, than disposables could ever be.
But, honey, we're saving the planet for our children...throwing away a Mach3 makes AlGore cry!
