This is a nice quality tool. The reason for not giving it a 5 is that it will only work with a full height nut. On a short nut the pin rides up over the edge of the nut . This is not mentioned anywhere on the packaging.
Although this device appears heavier duty than my 40 year old nut splitter, its design leaves something to be desired. My old one had a floating head in a socket, and it adjusted well to the flat side of a nut. This new one has a fixed head with a rounded tip, and because it rotates with the device's bolt rather than staying still like it should, it tends to slide off the nut. It may work better on large nuts that more totally fill the pocket, but If I can find a better design out there, I will be taking this one back to Sears. To work more effectively, one would have to drill an indentation in the nut for the rounded-point head to seat into, so it would stay there long enough for the cutter to start digging in on the opposite side and split the nut. The reversible cutter could be an advantage, but turning it upside down did not help when the rounded head kept rolling off the opposite flat.
Great tool. What I have expected of a Craftsman tool for over half a century.
Well-made and solid tool. And Craftsman so you can replace if it breaks.
Was too larger to use for my current need but I plan to use it in the future.
Really effective when restoring old cars
Nice to see it's still USA made. I needed one for my other garage and was able to get this one via ordering online and pickup in store. Arrived quickly.
