Lift and cut shavers

Pretty suprised that no one has asked this yet/
Are lift and cut shavers allowed?

Yes.

do you have to modify them at all? need a hechsher. also woukd you mind explaining the reason please? thanks

You do not have to modify.

There is a shield so it is not an issue.

why isnt it mispraiim ceein taar

why isnt it haschasa derech giluach

Because there is a shield that blocks the skin of your face from touching the actual blades. A “taar” is only prohibited when it touches your face. So regardless of how well the shaver shaves does not therefore constitute an issur.

What about the Norelco One Blade ?

This is fine. There is a shield separating the cutting blade from the skin.

So we can use the Norelco OneBlade directly on our faces without the attachments shown in the picture?

Here is a description of how the “blade” works: As you move the trimmer head along your face, the hairs will fall between the teeth of the comb and get cut by the rapidly oscillating blades. The green tips are a protective coating that appears to help prevent irritation that is normally caused by a metal comb being dragged along your skin.

Correct. Norelco one blade is the same as any other shaver.
