Yes, or a single one that takes a wide range of construction possibilities,
like strings, lambdas or regexes in various keyword parameters.

BlockReader(f, start='>')
BlockReader(f, start=re.compile('>|<'), end='---')
BlockReader(f, start=lambda x: x.startswith('>'))

Maybe make variations for character-based readers and line-based readers.
