Decided to do a field trip to the Shave Emporium and the Mrs. decided to come along. Not much of a store front, but the lady there was very helpful! (can't remember her name) Ended up with my girlfriend spending the majority of the time talking to the clerk about shaving her legs with DE razor! So she picked out a brush she liked and some soap for lathering. She shaved with one of my DE razors and now she's a convert! Caught her looking at safety razors on-line... Oh, and by the way, she watched this video...
Now the trick will be keeping her out of your gear but that's a good problem to have. My wife enjoys using my soaps but haven't convinced her about using a DE yet.
Now you can buy yourself a soap and pretend it's a gift for her. It must be great to share this hobby with your wife.
