SIR, — Leslie Adrian is very kind to can . o peners. MY own experience

is that there is no such thing as can-opener that will open any can. Nor should openers be necessary. I don't know what a seAu; opening' can is, but why can't all cans be made either (a) with a key, like sardine cans, (b) with lid and a sliding spike cutter, like coffee and cigar" r ette cans, or (c) with a separate lid that has a rube,, sealing ring that makes an airtight joint betweeP_ it and the can (the ring is simply pulled out hY", tab at the corner of the can) like some cans ei; smoked salmon from Norway? Perhaps Liesld Adrian could train some big guns on the whole ,,11,
