A very valid concern, to be sure.I can't whether they were allowed 39 years ago in USAF basic. But see how long it takes to clean an electric razor to be "inspection-ready" i.e. not a single whisker remnant anywhere inside. That ain't happening and it's gonna be hard and time-consuming enough to get them all off the outside.
However, these washable ones are basically 100% clean after a super-fast rinse under running water. Splish, splash, wipe it down, done. Like 2 seconds, no joke.
A VERY different gig from the old fashion electric shaver brush for cleaning, which took a long time and was never really perfectly cleaned out even after a lot of fiddling around.
I realize the Sgt. will be picky as hell on inspection, but I honestly think the washable electric will work fine with a lightning-fast rinse and a drying swipe with a towel.
That said, I want to make it clear that this is only a suggestion for one possible way to deal with a situation (basic training) that demands super-fast shaving that yields an acceptable outcome. For myself, electric would be the only option, because I just cannot shave very quickly and acceptably with a blade. I need time for prep, lather, 2+ passes, cool-down after-shave splashing, etc. For me, it's a 12-14 minute gig start to finish.
Under normal circumstances, I consider that 12-14 minutes to be time well spent, and I really prefer blade shaving. However, if I could only have 3 minutes, I'd personally have to go electric.
Anyway, it's a challenge and I hope it all works out!
