Adapter for small 1/4" ratchet screwdriver to take Leatherman bit tips
The Leatherman bits are standard hex sized only flattened.  They should fit in any standard hex that is open or deep enough for the double sided bits to fit.  

However be warned, without the custom sided attachment to grip the long thin side, the reduced surface area is more likely to round off the bits or the tool under significant torque.



Although Leatherman apparently doesn't think it's a problem as their bit extenders have a standard hex on the end and show it holding these bits.
