Why didn't L check Light's handwriting?


Why didn't L check Yagami Light's handwriting and try to match that to the
handwriting in the Death Note when he had the notebook?




L had foreseen that the handwriting could be faked. Actually, handwriting
comes up later in the story:

> One of Near's subordinates created a fake Death Note containing the names
> Mikami had written. Mikami didn't notice this since the fake book had "his"

Also, handwritings are not that distinguishable from one and another. It is
very likely for some people to have the same or similar handwriting.

As a side note, we can try to do a similar experiment by showing someone we
know our handwriting using our non-dominant hand. I practiced this before and
the person didn't notice that it was me writing it, despite knowing my usual
handwriting.
