Review on Bosch HS2163 Narrow Chisel Hammer by Juzer Rashid

IMHO I gave it 3 stars although I haven't tried it in a jackhammer yet because you have to rate it to be able to comment. {Why doesn't Revain allow "Comments Only"?] The image is misleading. The working end of the chisel is not proportionally wide as shown in the picture; it is narrow, only slightly wider than the shaft. The measurements given are wrong (as it often seems) in relation to the width of the blade. Even the shaft should be 1 1/8 inches wide = 1.125 inches, not 1.6 or 1.8. It seems that dimensions are often misleading as they may refer to the packaging and not the product. Where do you measure on a hex head? On the flat side of the hex or point to point on the hex? I measured the width of the 1 3/8" wide blade which is only 1/4" wider than the 1 1/8" shank size. Is the blade width listed in the description?
