comment How does one make a double widehat?
No actually I do still need the redefinition. Suppose I have two files. One uses amssymb and one does not. To get the output in the second picture above when I also have amssymb, I have to use f\, but I can still use \widehat{\widehat{abcd}}.

comment How does one make a double widehat?
Thanks for the responses! For completion, I should remark that if I have \usepackage{amsmath, amssymb} in the preamble instead, the above trick reverts to the standard behavior of \widehat{\widehat{f}} that occurs when you do nothing. To get around this, it seems that at least for double widehat-ing single letters one does \widehat{\widehat{f\, }} with the code in the answer above. However, for multiple letters like abcd, using amssymb doesn't affect the output of \widehat{\widehat{abcd}}
