Mea Culpa.... But I didn't think the term-of-art was "Snow Pusher"...
hence the suffix... but it turns out that's it.

Like this, only about a hundred years old:

I didn't know they had webpages 100 years ago.

But I googled and some rancher found one in a dry cave in New Mexico
that appears to be 150 years old. It's unusual because it has a date,
when most current webpages don't.

The one you post above is intriguiging. It says it has a
"self-sharpening blunt square surface". I guess it only sharpens until
it's blunt.
