...but it's making me crazy. The old style can opener blade on slipjoints like old Scout knives. How did that work? I cant picture it in my head. I'm sure it's obvious....but not to my brain. :D Thanks!
 
The bottom latches on too the rim of the can the top Blade cuts through the top of the can with a levering motion. Hope that helps my friend!

Or if you have this type of can opener. I was thinking of this one:

Legion, I'm thinking was thinking of this one:

The nub rides on the rim. You rotate on the nub to push the blade edge into the can and work it around.

I am thinking on the bottom one in your subsequent post. I'm just not seeing how it works! I'm sure it is incredibly obvious and it's making me crazy.
 
OK. The one on the black scout knife (Not the very, very nice looking Schatt&Morgan...wow!).

What part is up? The thing with the nub? Is the knife parallel to the top of the can?
 
Ahh~ brings back memories a slightly bean-sticky spot needing to be cleaned off a knife, and a levering callous on my finger... On past occasions I've gotten so frustrated with conventional can openers, that I've whipped out my SAK and skuttled around the rim of a can before a dude has even 'set the edge' of one of the big commercial top-crank opener beasts. Still one of the best ways to cut one's thumb since the ole days of pull-tab beer and soda cans!

You stab the curved part straight into the top of the can the (nubed) part sits on the rim that gives you the leverage to cut through the top.

Sorry...I must still be having brain problems. So you lever it towards the nub part and cut with the inside of the curved part? Kinda go backwards?
 
Thanks to fellow member Kadmos....I got it figured out. Cut with the inside of the curved part by going up with the knife parallel to the can and levering on the nub. zi think thats a certain class lever if anybody remembers science class. I don't! :D

Thanks to everyone and Happy New Year!
 
The interesting part to me is the transition from a upward levering motion that cut on the up stroke to a upward levering motion that cut on a downstroke. I wonder what brought that change about.
 
I would think logic brought about that change. :D It has got to be easier to lever down on something resting on a surface than to lever up and have to counteract lifting it off the surface.
 
Maybe. But with the "lift" style opener you can actually punch a hole into tin without having a lip to work with, such as a flat sided container. Can't do that with the other ones.
 
I'm curious about the timeline of the different styles of can openers . I have seen scout knives advertised as 1940's that had the lobster claw style can openers and I believe this style came out much later than that.
 
It works by basically tearing the lid off as you heftily lever it around leaving a very jagged edge.Also you have to apply a lot of force and leverage to reach the contents of the can such as Baked beans(yum), Kidney beans (drool), dogfood(slurp),soup(scrummy) .etc.

The safety can opener was patented after 1944
