Pyramider i Egypten
"Many of the casing-stones and inner chamber blocks of the Great Pyramid fit together with extremely high precision. Based on measurements taken on the north-eastern casing stones, the mean opening of the joints is only 0.5 millimetres" ("0.020 in)
"The pyramid remained the tallest man-made structure in the world for over 3,800 years,[6] unsurpassed until the 160-metre-tall (520 ft) spire of Lincoln Cathedral was completed c. 1300. The accuracy of the pyramid's workmanship is such that the four sides of the base have an average error of only 58 millimetres in length"

"The only object in the King's Chamber is a rectangular granite sarcophagus, one corner of which is broken. The sarcophagus is slightly larger than the Ascending Passage, which indicates that it must have been placed in the Chamber before the roof was put in place. Unlike the fine masonry of the walls of the Chamber, the sarcophagus is roughly finished, with saw-marks visible in several places. This is in contrast with the finely finished and decorated sarcophagi found in other pyramids of the same period. Petrie suggested that such a sarcophagus was intended but was lost in the river on the way north from Aswan and a hurriedly made replacement was used instead." Wikipedia
Texten ovanför talar om märken efter såg i granit.
​
Enda problemet är att egyptierna inte hade diamantsågar eller sågblad av tungkarpid.
Det är totalt omöjligt att såga i granit med brons- eller järnsåg.
Metalsågblad klarar inte ens att såga en halv centimeter i granit.
​
Även marmor var omöjligt att såga i med bronssågar.
