Wow only one post and the thread is already off topic!
We do a large-scale meat and chicken delivery order for my neighborhood. Before Pesach two years ago, I was between razor cutters and the cases needed to be opened. (Even though not halachically an issue to use my chometz knives, you know how antsy people get.) Luckily one of the first to show up was a mohel - and he gave me one of his disposable milah knives. (It is
very very sharp, even now.) I keep it with my Pesach things and use it to open the meat and chicken boxes every year.
New thread: what kind of cutters do
you misuse?
