I have had two Stanley's thermoses. I left one on a rear bumper and it was run over by a heavily loaded one ton. It was not on pavement though so I only lost the cup and part of the cap. Still worked fine but held less so after a time I replaced it with another. Like so much that was made right they are not the same anymore and are produced elsewhere.Not Stanley Rule and Level co.
but...Landers, Frary & Clark of the Stanley Insulating Division...New Britain CT.
Haha, I read this same article this morning. The one I came across is only about a 1/2 mile from my shop. And it was only $5. It has the little channel piece with the wing nut. No fences or blades. If you need me to grab it to fill any voids in your life let me know.
edit: unfortunately I don't have one, oh well . . .
The pitting on the backs is a concern because that needs to be lapped out before you can create a true edge.
A No 4, type 16 from the 30's (I think!) to clean up & a nice screwdriver.
