Ooo,I like that. #17 very clever,never seen one like that before. I like the idea of being able to drive the bit from the handle. Its on my shopping list for this evening along with a new 1/2 drive torque wrench as I'm fed up not having NM as its so old. probably not super accurate anymore either due to its age even though it's never been dropped and I have always unwound any torque settings before putting it to bed.
