Kosher Electric Shavers

Question

Which electric shavers are halakhically acceptable for shaving a man's beard?

Answer 1

According to this article from the Zomet Institute, even unaltered "lift-and-cut" shavers are permitted lechatechila.

Answer 2

Please note that there is a potential Torah prohibition here. As always on mi.yodeya, please ask a reputable Orthodox rabbi.

There is a variety of opinions on this matter but the range seems to be from "there is no such thing as a kosher shaver" to "there is no kosher 'out of the box' shaver currently being sold." According to the latter view, however, Norelco Lift-and-Cut shavers can be modified after purchase to be halachically usable.

Answer 3

There is a site dedicated to explaining how to make a Norelco "lift and cut" shaver acceptable for use (http://www.koshershaver.org). In their FAQs they quote R' Dovid Feinstein as ruling that no other brands currently on the market are acceptable without modification.
