Bests & Worsts Reviews from Amazon

EDIT: Downgraded from 3 stars to 1 star and ultimately being returned. I originally figured these to be ok for woodworking. True, they are decently square. However, the fact that the blades are inserted into the body at such a skew, means the blade will not lie flat to the work-piece when registering the body against the side (think "striking a line perpendicular to the side of a work-piece"). On every single square, the blade is either completely lifted off the work-piece, or only the very end of the blade contacts the work-piece. These are junk. Either people got lucky with theirs or they don't use them the way that I do, and the defects can be overlooked. Original review: The short version: I am using these for woodworking and they are *just* good enough for that. These cannot even remotely be considered a machinist's or precision square. The grinding, fit and finish are simply much too poor. These just arrived today, and I immediately set out to determine their accuracy. Using a granite surface plate, a pair of known to be accurate 1-2-3 blocks, a machinist's straight edge and feeler gauges, I began testing these. In the planes in which they are used, squareness is very good on 7 of the 8. (4 squares, square inside and outside). The issue lies with the 4 inch square, in which the blade contacts the test block very close to the body and begins to run out from there. It's very detectable against a lit background, and is more than .002 - less than .0025 over (just under) 4 inches. It's also very apparent that the issue is not really squareness, but rather poor finishing, as the gap is very consistent for most of the blade length. I'll probably grind away the high spot next to the body, retest and at that time, choose whether I want to avoid the inside face of the 4 inch square. Very disappointed, as that's the square I would probably reach for the most. The blade edges are all quite flat when registered against the straight edge, except the inside blade of the 4 inch. Again, the poor finish there is the culprit. Overall, the finish is rough. Lots of little dings, chips, burrs. They will take a couple hours of careful work to improve/correct. Now, the most abysmal part of these. Not one blade is inserted into the body straight. Face the blade toward you, these are clownishly crooked. (See pictures). I am not at all expecting precision in that plane. However, this smacks of utter disregard to workmanship. I feel like it took effort to make them this bad. It pains me to keep these, but they'll be ok for woodworking.
