Ingersol, yep, have the same opinion... Still have a MAC234 (Ingersol made) double hammer.. That thing still whips ass!!! Kinda heavy, compared to the newer ones... But none of the newer ones come even close in power... Plus it has grease zerks, and oil reservoir in the grip... Gotta love that attn to detail...
The Snap/On line wrenches are def better than the MAC units, neither will slip, (although line nuts do collapse inside the wrench).. But the Snap/On units have narrower ends, which allows them to fit in places where the thicker MAC ones won't fit, (like pressure lines on steering racks, where the fittings are very close together)..
Same goes for Crows feet... Over the last decade Snap/on has been subcontracting some of their tools too..
Very dissappointing!!! But I suppose that its the "way of the world" in this day and age...
Actually, I have been out of the "Car Biz" for a long time now.. Gettin too old to bend over fenders anymore!!!
But I did very well in life thru that business.. Got me everything I ever wanted...

to all the bruised knuckle wrench twisters out there!!!
