Of course, buying a second shank would’ve been the obvious answer, and the total cost probably would’ve been similar to a set of one-piece bits, too. Come to think of it, storing disassembled bits and shanks probably takes less room than the one-piece style, so I’m gonna say these are ideal only in situations where the tool spends more time out of its case than tucked away.

Of course, the one-piece bits could turn out cheaper than the mix-and-match style, so perhaps they’ll be attractive to the casual market too. Wait and see!
