We all know them: those handy little folding can openers.
Connoisseurs have their favorite brands: Speaker, Shelby, Mallin, Kay, and others.
But what I want to know is: what kind of metal was used?
Certainly not a high-chromium stainless. They aren't shiny. And they are plenty magnetic.
And yet I've never seen one rust!
How about the hardness: anyone know what the Rockwell number is?
Is it different for the blade and for the handle?
Even more basic: what's the Rockwell number of your average soup can?
One reason this is of interest: titanium.
It's difficult to get titanium harder than around 35-40 HRC, which would be unacceptably soft for a knife.
But maybe it's harder than a tin can?
So could you make a titanium P-38?
Personally, I wouldn't. Part of what I like about the P-38 is that it is dirt-cheap, almost disposable, and you can use it to do the dirty work, whatever that may be. I don't want a diamond-inlaid P-38, and I don't want a titanium one.
But is it possible?
And what kind of steel are the ordinary ones made from?
