I totally agree with Sawtooth being created based on Dirk's Bro. And expanding on that, he was based on a very young Dirk's idea of like this mythic ancestral figure. So even if later in life Dirk is more about like, being a "realist" and viewing his brother with a whole salt shaker worth of salt, Sawtooth is like this snapshot of the mythic hero/older mentor figure/caretaker young Dirk thought his brother was. Which explains why Sawtooth is a badass in basically every conceivable way.
