I like them a lot, but this particular one you can put under a 90 degree angle, creating great torque with minimum effort and strain on hand and fingers.Really? I've never liked that type of "boiled sweet" screwdriver handle.
I worked at a company where these were used a lot to undo rotten bolts, in cast machine frames, some collegues hit on the hinge with a 250 gram hamer all day long, saw only very few break. Virtually undestructable.
