Mashgiach Rabbi Ari Elbaz demonstrates how to check a Chalef knife for kashrus purposes

And that's where we learn out the what does mean according to some that that of that meaning the main which is that the knife should not have any dent in it any is not even we know the five are but some hold that that the fact that it shouldn't have a dent in it the is not even because the translation of the word va as it says in the par regarding means cutting only >> and once there's a pigma as the explains in in the the daffy yesterday and today once there's a piggy so in that spot when the piggy passes across the neck of the behem it's not doing a straight cut it's pulling it and and ripping in that part and therefore therefore it's not a kim of vizaka and that's why when it comes to knife it's extremely extremely important to have to have um a knife that's completely smooth top to bottom without one drop of a pigma. is people don't understand what it means to be pigma and the the first many times that I touched the knife and checked the knife I didn't even a pigma we think of a pigma as you know well we take out your kitchen knife you know of course you'll feel lot lots of bumps in it but when when you're working on a knife for a long time and you think oh I'm done because it feels so smooth and you're not going to realize a pigema doesn't necessarily mean what you're used to thinking it means even something tiny which you don't even notice and you have to you have to get your mind used to noticing That's also pigima. So over here we have a knife. This is a very simple knife for chickens. Not for obviously not for goths for for animals. So this is a typical knife. And as you see the knife is extremely smooth. Now are there piggyas? Hopefully not. But just because it looks like this does not mean that there are no piggyas. So the mar says we do yud bay pedikas 12 pedikas. Why? Why 12? Every time you go up and down it's two. Up one down one is two. >> So that says do it on three sides. The middle and the side on one end the side on the other edge. Both edges up and down. Of course there could be a beginning on the side but not right in the middle. And that's already six. Garo says we do it. Not just with our fingernail, also with our buser running across our flesh. The mic today is not really to do that. We just we're on on our fingernails. So the way to do on a saken would be, of course, you have to hold the knife in a strong position. Make sure it's not wobbling, not moving. You start with your with your nail from the bottom. Oh, you got to make sure your nail is not in in a crazy in a crazy uh circumstance. If your nail is not properly sharpened, by the way, and I mean this the do actually they they shape the finger down the way that that it shouldn't it shouldn't um make believe there's a pigma should also smooth. >> You start from the bottom the very bottom because there cannot be any spot with the pigma. You start from the bottom and you slowly you go up with extreme concentration. >> How many times a day do I chuck the knife? >> Oh, it's a good question. But because I said extreme concentration, I'm not going to talk to anyone while I'm doing this. >> Okay, that was down the middle. Now on on one edge up that was ba three and now down >> and now >> on the other >> how do you know how much pressure to apply? It's a good It's a good point. Happens to be that's okay. One second. >> All the pressure on the tire. >> I don't like that. So, I felt something. I don't know if it's necessar because like you're all thinking, maybe it's my nail. Nails do get a lot of dents in them just from going up and down the knife. So, we have to clean off on something which we know is not going to make the piggy band any worse. This is a common common uh way of the shenan just to wipe wipe it off quickly. You don't want to do it on the floor of the table or the wooden shelf. And let's try again. Where are we over here? It's actually better. Which means that what I felt before was probably just a piece of piece of my nail that came off. Okay. Okay, I would say the knife is kosher but not mud. Hasn't been worked on in a long time. And for all those that are interested, we'll we'll give you a chance to go up and down the knife. Do not try this at home. Uh make if if you're not sure if you're not if your nail will handle it or your nail's too short and you may not uh limit it to your nail, then I don't suggest you try it. actually. So you're going to do your tongue, but >> right says that some would do it on the tongue also. But if we don't even do it on our hand, then we definitely don't do it on the tongue. The way to do it on the hand would be not to slice your hand off obviously would be to run either straight down or the other direction. >> I could actually do it on my saying show you on that show. >> Um it's okay. It's a really smooth says >> bisra and bisradica >> the knife cuts basar meaning the behem and therefore that's how you should check the knife on basar too that's why we do it on our hand so I'm going to pass around anybody who wants to do bika and I'll I'll show I'll show on on a big one also So the way hold this is you put the handle over here on your elbow on your elbows like that and and you hold it over here so you you have much more support and then >> holy god >> you run up and down >> that's not a knife. You want to see >> children? >> It's like a classic. >> Not bad. jokes. >> So, this is cutting. This isn't a joke. >> No, it also has to be that thick. You can't be so hold >> like this. First of all, strong lost in the neck. >> Yeah. >> So strong. >> Yeah. Yeah. That's for sure. Like even this is strong. By the way, these aren't weak knives. These are strong. >> Yeah. So the daff is talking that's where it's from. >> It's actually pretty good. I would say it's kosher. Maybe not the best, but I think it says kosher. And I'll just enough of the one line which is which is brought down just to show you how serious what it means to to be a like this. >> Anyone want to try this one? Be very care very careful. How do you say it's better to be a little bit rounder so it doesn't have that? Yeah, very good. Yeah. So, Hungarian Abad very rounded. Yes. Well, no. What was it's been? >> So, >> it says it says that there's a remed and most professor says that's to and it just showing the knife as showing the check knife. Some say what's gamatria >> 12 is gamatria 12 means with the 12 badikas you make 12 bikas like we just showed up and down three sides and then with with your flesh also that equals 12 careful careful with that >> and just I don't know if you want you want to call this part two there was one brought down brought down the pisk was fired from his job for not remembering that Gimatria of Baz. >> Wow. >> Which city do you think it was? >> Which Frankfurt? Frankfurt. >> Frankfurt. Maybe there too. >> But the one brought down is Brisk. >> The was fired. >> It's not so strange. is eating nut.
