What kind, and where are the tools used to construct the pyramid at Giza?

Since granite is hardness level 6.5 this would require either diamond tipped tools or perhaps iron-carbide rotary saws and such. Some of the inner granite is high in Quartz crystal, likely due to it’s piezo-electric effect, which is level 7 hardness.

Could it be that high pressure water tools may have been used? This might explain why there are none left to this day. Here is a video showing water used to cut granite: https://www.youtube.com/watch?v=XuTV6HiPyi8
