Dear Rabbi Simon,
Can you please tell me if the following shavers are kosher? Philips New Series 3000 Wet or Dry Men’s Electric Shaver Philip series 6000 wet and dry men’s electric shaver Philip series 9000 wet and dry mens electric shaver Philip series 5000 wet and dry men’s electrical shaver.
Thank you for your question.
My experience over many years is that Philips shavers use only a scissors action rather than a razor and are therefore acceptable for use. It has been observed, however, that the same is true for nearly all contemporary electric shavers. See here: https://www.zomet.org.il/eng/?CategoryID=253&ArticleID=141
As shaver models change continuously, it is very difficult to keep up with the details of a particular device. Nevertheless, in halakhic terms, the technology does not seem to change fundamentally.
I hope this is helpful.
Rabbi Rashi Simon
