Klaf al tnai
Today I was in a klaf store in Bnei Barak and a seemingly secular woman walked in asking for "non-kosher klaf" that she can use for calligraphy. The seller gave her Grade B klaf to look at. It raised some questions.
Is it the act of being mekadesh to write L'shem megilla for example that changes the property of the klaf where now it is considered holy and needs gniza.
Ma nafka mina: For example if one were to start writing a new pair tefillin, say l'shem kedushas teffilin, write the first letter, and then make a terrible mistake that is unfixable like huge blot of ink. Now he needs to throw this klaf away, was he mekadesh the klaf which is made al tnai, or no?
Hope everyone understands the idea.
