Just had a stainless table knife shatter … while cutting a sandwich. It looks like maybe water got in through a small crack?

@adamshostack Or you are very strong

@adamshostack

the smallest porosities in metal can cause failures. crack is a good alternative theory.

@adamshostack looks like you were trying to cut a candle with it. 😄

@adamshostack Maybe the bread had a +5 crust of hardness?

@SteveBellovin as it turns out, super soft bread, fillings, and the knife snapped in the middle of the sandwich. It was really surprising.

@mweiss wax on..

@paul_ipv6 Somone else mentioned the term "crevice corrosion"

Their posts are set to follower only, so not retweeting/naming, but I learned a bunch digging into that term so wanted to share.

@adamshostack

thanks!

yes, metallurgy is fascinating. much like humans, stunningly strong and yet vastly fragile.
