Get a mitre box. Much easier to use.

But a mitre box doesn't have any guide 'clip' to stop the saw wobbling
in the groove. The clip was the JointMaster's secret weapon.

Dad had one of these Jointmasters back in the '70s. Neither of us ever
found any use for it.

On the contrary, back then I sawed many pieces of wood nice and
square. I reckon it was and is a genuinely useful tool. But the clips
are both its secret weapon and its Achilles' heel.
