Also the material is aluminum? The one I have in my house is steel.

Also I debug learned all the recipes and I don't have it.
I'd make one but I'm not 100% on how to make a recipe, especially how to put it into a book and not fuck it up.
I'm thinking steel, full forge rig, fabrication 2?
Fab 2 can make pliers, blades, and ball bearings.
What book or books would be good to put it in?
Try adding it to textbook_mechanics using "book_learn": [ [ "textbook_mechanics", 3 ] ],
Can sealer has pretty high number of parts in it: https://www.youtube.com/watch?v=nzape-rNQ5Q.
Blades should be easier to make.
That head part is cast metal with lots of detail, doesn't seem like something you can make with a forge.

Considering the things that we can already make with fabrication, I don't think it presents a problem.
Hmm, given the second example, nevermind, it looked like it needed to apply
vacuum while it was sealing or something, if it's just crimping the can it
seems reasonable.
Hmm, as far as I can tell, canning with actual tin cans isn't typically done in home canning, mostly being glass jars. That said, sealing a tin can is mostly just crimping a slightly wider circle of metal over the open end of the can. It is slightly more complicated than that, and I imagine a DIY variant wouldn't be as good as a commercial grade machine. That said, I imagine that even the DIY version should be able to achieve the "prevents spoilage for at least 1 year" criteria.
You add some water and anti-rotting agent (like sugar or salt) to your product, boil it, make vacuum and seal the container. Pickles or jam will most probably last unspoiled for at least a year.
