I have used Kline for years and never had a complaint they also have lifetime replacement at the supply house. Greenlee also makes top notch stuff don't know about replacement tho. Proly boils down to price I'd say.

good luck which ever one you get.

 

Nothing wrong with either, but I see most professional electricians using Klein.

 

The Greenlee price went from $29 to $24, and the Klein is on clearance and went from $39 to $29. The Greenlee seems to be a little more heavy duty....not saying its better. The Greenlee has more of a polished finish and the Klein has more of a chrome finish. Both are stainless. Both have lifetime warranty. Both have rubber handles.

 

I will agree that eiher of these are good tools. Note the Greenlee set states they have tubular shafts, which will allow you to use them on longer screws. I have more than one set of nut drivers and my set with tubular shafts will find more use than the others. Thanks,David

 

I ended up purchasing the Klein set for $29. Thanks for the advice.
