The opening of this shiur, in Rabbi Daniel Glatstein’s own words — taken from the captions, so names and Hebrew terms may be approximate.

Okay, good morning everyone. We're continuing Hilchos Netilas Yadayim. You know, when you learn Hilchos Netilas Yadayim, you see key toyvim d'oraita miyam, chavivim divrei soferim af miyeino shel Torah. The profundity of Hilchos Netilas Yadayim is as amuk as any metziya in Torah. Okay, we're up to sif hey. We're going to try to do today sif hey sif vav, perhaps and beyond. And then we're going to go back and see sif dalid. Basically, what we want to clarify is there are many different levels. The biggest problem, as we'll see, is if a different person touches your hand. Next level is if a hand that wasn't washed touches your hand. It's a problem and perhaps even if he used a revi'is. Certainly, it's a bigger problem if you didn't do a revi'is. That's what it came out from yesterday. Regarding wet um kli handles, according to Mishna Berurah, it's only initial if you don't use a revi'is. Other acharonim bring other potential problems, but let's we'll re-examine that tomorrow. Today, let's go further. Mitoch masha kesavnu yizbar lacha. Based on what we wrote, it will become clear. Deha dyad nitma bishvil shulchan If you remember the beginning of sif dalid, the beginning of sif dalid is if you poured water on one hand and you rubbed it into the other hand, uh you're up the creek without a paddle because now each hand has tum'ah from another hand that cannot be removed. But based on what we wrote, that one hand becomes tum'ah rubbing with the other davka benoitel yadai achas, it's only if you washed one hand.
