Talk:Can opener

message: A bayonet tin opener is the one where you stab the tin lid near the edge and work around - they are not very common, but they are very robust and do not break. On the other hand they leave an ugly irregular opening. They have no moving parts. 
All-metal 'top-down' openers are also common where I live. They cut down into the lid, rather than into the side of the can near the lids. I do not know what name they have. Instead of having a rotating circular blade like more recent openers, they just have a non-moving small 'plough' that splits the metal.  
I am aggrevied that I have to keep buying a new can opener every few weeks. In particular, they are often damaged when I try to open those small oblong sardine cans. Reasons why they stop working:
# The serated wheel wears down (rapidly) and loses its grip. 
# If the wheels are held in plastic, the plastic breaks. 
# For the all-metal top-down openers, the metal things that positions the opener on the side of the lid gets bent when I try to open sardine tins. They also suffer from (1). 
# The spindle holding the wheels in place comes apart. 
# Things that should not rotate around the spindles rotate around the spindles. 
# Things that should rotate around the spindles do not rotate around the spindles. 
Even my reliable bayonet opener is starting to get blunt, so stabbing the can has become more difficult. 
This is a list of all the different types of tin opener I can remember ever seeing or using:
# The most recent type with two spindles, one of which has a gripping wheel and the other a cutting wheel. Usually cuts side of can near the lid. 
# Older type with only one spindle which has a gripping wheel, with the opening being done by a small 'plough'. Cuts lid of can, as do all those below. Still very common in UK. 
# Bayonette type - no moving parts. Rarely on sale. 
# Small folding, referred to in article as the P 81 I think. 
# Lever type which makes a triangular hole in the lid of the can, suitable for pouring liquids. If many such holes are made around edge of lid, then the lid could be opened. I have not seen one of these in decades. 
# Flat type apparantly supplied in some penknives. I cannot remember ever opening a tin with one of these, and I am not sure if they actually work. 
I would be willing to pay a lot for an opener that lasted for years, not weeks. 81.104.12.10 01:24, 30 November 2006 (UTC)

message: I believe a "can opener" in ice hockey is when you stick your stick between somebody's legs and trip them. As there is a section for military slang, should this be included as well? Canking (talk) 19:13, 18 January 2008 (UTC)
replies: text: At most I could see a brief disambig. sentence at the top of the article with a link to some other article.  The military section is about military can openers, not about some military slang/jargon phrase "can opener" of a different meaning.  Hockey slang doesn't belong in this article any more than alcoholic beverages belong in an article entitled "Screwdriver". - Blueguy 65.0.209.205 (talk) 06:07, 1 October 2009 (UTC)

thread_title:  Bias?

message: The end of the article mentions side-cutting can openers, but only mentions the kind that cuts into the rim, so as to leave no sharp edges, but there are other can openers which cut just under the rim, cutting the whole lid and its rim off, leaving a sharp edge all around the can, but not the lid.  The designs of these look nearly identical to the others, but for a very slight change in blade position. - Blueguy 65.0.209.205 (talk) 06:15, 1 October 2009 (UTC)

message: None of the images in the "Church key" section represents the classic "church key" bottle opener.  The original church key design is made of heavy wire, and a Coca-Cola branded version from Germany can be seen at :File:-_Coca-Cola_-_Old_bottle_opener_-.jpg.  It superficially resembles an old-style door key and pre-dates by years the combination can piercer/bottle cap opener on which the section dwells excessively. — QuicksilverT @ 21:16, 5 March 2014 (UTC)

message: There should be a brief section on the can openers found on Swiss army knives and multi-tools.  I'm not even sure what style of can opener that would be; of the ones on this page, it's probably closest to the P-38, though isn't there another style of one-piece can opener that you work around the rim that's basically the same as on a Swiss army knife?

message: It it a good idea to
* move this page (Can opener) towards Can opener (device) and
* redirect Can opener to Norfolk Southern–Gregson Street Overpass? --ManuelNeuerFan1 (talk) 14:35, 23 May 2021 (UTC)
replies: text: For me, I would think of the device first when hearing "can opener" or "tin opener", not the bridge. There is already a hatnote on this page directing readers to the article on the bridge, so I don't think moving pages is necessary. On the other hand, the bridge article gets more views than this one. I still think the titles should be kept the same. NemesisAT (talk) 15:56, 23 May 2021 (UTC)

message: RE: "A new style of the can opener emerged in the 1980s...."
This is incorrect.
Edwin Anderson's opener removed the entire lid:
Star / Star Can Opener Co., San Francisco, CA / can opener / patent 1360256 Nov 30 1920 & 1528178 Mar 3 1925 & 1598841 Sep 7 1926 Edwin Anderson / see also Turner & Semour /
The same can opener was also manufactured by Turner & Seymour Co. as the “STAR” brand can opener, stamped with all three of the above patent numbers.
In addition to the aforementioned can opener, Turner & Seymour manufactured a number of other items.
Turner / Turner & Seymour, 100 Lawton St., Torrington, CT 06790 / est. 1848 / "KING" can opener, combination corkscrew, "STAR" brand hardware & tools / patent 1360256 Nov 30 1920 & 1528178 Mar 3 1925 & 1598841 Sep 7 1926 Edwin Anderson & 541034 Jun 11 1895 William G. Browne & patent 896577 Aug 18 1908 C.W. Reynolds / https://mycompanies.fandom.com/wiki/Turner_%26_Seymour_Manufacturing_Company / see also Star Can Opener Co. /
The aforementioned patents 1360256 and 1528178 were both subjects of a series of patent infringement claims filed by Star Mfg. Co. against several other manufacturers.
Star Can Opener Co. vs. Ace Mfg. Co. US Seventh Circuit Court of Appeals 3837 Oct 1926

These two European patents were issued prior to Anderson’s first patent, but neither of them were ever manufactured. They were used as evidence in the cases above:
Weigel patent (DE 282768) (plaintiffs exhibit) pp 26
Wolfer patent 1024543 (plaintiffs exhibit )

message: the first star roller can opener, from 1853, saw the date on the side! first can opener, way before that! sometimes the truth will get out there! its much like the Sad Irons, some think they were made in the beging of the 1800s early! false, they were being made in Sweedon, 1648! by Husqvarna! called coal irons, and then later iron plugs put inside and could be rotated for longer use!

thread_title:  the Star roller can opener was mand in 1853, saw the date stamped into the side of it! so if their telling you the first one was 1870s its not true, just like like the first can opener, it was before that! fact not fiction!  Robert, Hall
