The Sears set is the same as those sold by many tool trucks and specialty stores. Obviously Sears didn't make them, but I speculate that they are probably made by a well known US specialty tool manufacturer such as Wilde or Ideal.
The HF set was purchased three years ago for less than $20 on a 25% discount coupon. A pretty good deal!! Here are the two sets side by side.
HF doesn't include as many pliers but includes two picks for loosening snap rings, while the C-man set includes four sets of three each (straight, 90 degree, and 45 degree) pliers.
A general overview doesn't offer much difference. Both sets have cushioned handles and are manufactured from about the same thickness of steel plate.
LOL -- HF says it's an 11pc set, but that includes the storage case. There are only 10 tools inside the case -- two picks, and eight pliers.
That said, the Sears design makes it easier to switch and align the tongs since it has a unique clamping system
The points on the tools are the same -- there is not much difference between tip grinding and design.
First the Sears then the HF -- note the HF tip is a bit off on my tools since I use this particular set a lot and it may have distorted a bit
Now for a smaller set -- HF is first and Sears second
All the other sets are pretty much in line with each other -- i.e., no large noticeable differences.
Here is the largest jaw comparison -- Sears on right and HF on left
Bottom Line: I really see no BIG difference in design or quality that would make me purchase the set from Sears for $244, but at a $53 closeout price it's definitely worth the money. Is it better than HF? Yes, in one respect -- the locking and alignment mechanism is better than the plain HF screw system, but the strength and tip grinds of the tools are even. I'd buy the HF set again -- even at full price, but since this HF set has recently been priced continuously at $15, it's a "no brainer".
