Price aside (Because you can purchase used Snap-on sockets cheap)......What makes the ICON sockets superior to Snap-on sockets? And what sockets are being compared here?
I bought most of my hand tools before all these choices were available.......You had the tool trucks (Snap-on, Matco, Cornwell, Mac), Craftsman, & Industrial brands like Martin, Proto, & S-K Wayne. Not going to run out & replace stuff......But curious all the same.
I buy mostly Snap-on for the service first & foremost, High quality is a real close 2nd. My rep has literally gave me extra replacement drives for my Breaker Bar, 1/2"-3/8" reducer, & T40 & TP50 bit sockets. If I call him.....He'll be at my shop in 30 minutes or less.
Supporting US manufacturing is also something I like to do.
