Just today I bought four old cookbooks from a thrift shop. In total there were three findy-things: a canned salmon label with recipes (including a salmon gelatine mold), an advert for a campaigning alderman from 1960, and my favourite - a handwritten recipe for 'May's best raisin cookies'.
It seems pretty stupid to me. Why not use the softer tips? It's plenty dangerous with them, anyway.
