How about this? Take a 1/4 adapter (hex on other end) and glue the blade to the adapter using J B Weld. It will be there long after you aren't. J B Weld has come up with a "QUICK" version of the old product. Avoid this. It sets up almost immediately and for tedious jobs, it has started hardening before you get it like you want it.
