Martin van Veen, senior manager at Philips Norelco, clarified in writing that this is how all current models and models in development operate. The 2016 video shows the shaving process from the outside looking into a high-end model, and the 2019 video shows the shaving process from the inside looking out from lower-end and medium-level shavers. The videos, recorded in 20, show the blade first moving hair toward the screen, and only after it is at the screen does the blade cut the hair. We believe that this concern is conclusively dispelled by videos provided to us by Philips Norelco in October 2020, along with a PowerPoint explanation setting forth ample scientific evidence that electric shaver blades cannot cut without the combination of the screen. Rav Heinemann is concerned that the electric shaver blade could cut independently from the screen. More broadly, we believe the test Rav Heinemann administers to electric shavers to be irrelevant. In his eulogy for Rav David Feinstein, Rav Yisroel Reisman mentioned that Rav David permitted the OneBlade shaver. Rav Yona Reiss told me that he administered Rav Moshe’s test to the OneBlade and found it kosher. Let us begin with a response focused specifically on the OneBlade.
This shaver will not work as well nevertheless, it is still effective and will transform a previously questionable shaver into one that is acceptable by the poskim who permit the use of shavers. This can be done by taking a key or some other hard, flat instrument and running it along the sharp edge of the blade. The only practical suggestion that can be given to one whose shaver failed this test is to dull the blades. Therefore, even according to the poskim that permit electric shavers, this shaver would be problematic because it would be cutting like a ta’ar, which is forbidden. However, due to the increased sharpness of the blades of the rotating heads, it is conceivable that the blades could cut the beard hairs off before the combined cutting of blade and screen. He would take a beard hair and test the blades! The shaver would be acceptable if the hair was held taut and was not split in half. So too, in a similar manner, R’ Moshe would often test the sharpness of an electric shaver’s blades. If the hair was severed, the shochet’s steel passed the test. To show the sharp edge of his knife, a shochet would take a hair from his beard, and holding the hair in one hand the shochet would see whether the חלף cut the dangling hair. Hagaon R’ Moshe Feinstein זצ”ל, who permitted the use of electric shavers, used criteria similar to the shochet who would demonstrate how sharp his חלף (shechita knife) was. Rav Moshe Heinemann presents how Rav Moshe Feinstein determined if an electric shaver functions in a permitted scissors-like manner :
