I think there is a problem with the design because the metal tongs move easily making separating the chalaza from the egg almost impossible. Six attempts and I've never been able to completely remove the chalaza. The old plastic chalaza puller worked much better. Unfortunately, this company has stopped production. The problem with metal is that even if you adjust the grips of the pliers correctly, there will still be gaps in the closure of the rounded part. I think a redesign would help.
