"As blunt as a widow's knife"

[EftlidtNZ]

Just wondering if anyone has heard this phrase before. It's used in Paul O'Grady's first book, but doesn't turn up in a Google search.

Don't know if it's something he made up, or a mistake for another phrase.

I've never heard it before! Presumably the implications is that women are incapable of sharpening their own knives, so a widows knives would have gone blunt??

I've heard the term "a widow's knife" which means something no longer fit for purpose. Not heard the blunt part before but it sort of makes sense as a blunt knife would be fairly useless.

Oh I assumed it was blunt cos she'd used it on hubby and made herself a widow and the knife blunt. Like a, cautionary tail

This is what I thought too
