Copper is not what is cutting the rock, the abrasive is...... copper oxides have been found in unfinished cuts that still have tailings and on cut surfaces.

It has already been demonstrated that 6mm blades can be manufactured by sand mold casting and used to cut granite with sand abrasive (Stock 2001).

Stock (2001) cut was straight...... he did no use a jig to hold the saw either. If the ancient Egyptians wanted extremely precise cuts I can see of no reason why they could not come up with a jig to hold the saw rigid.

There are no drill marks that I am aware of..... there are cylinder shaped holes near the corners of the obelisk, these were pounded out apparently so they could examine the quality of the rock with depth (and/or let some of the lithostatic pressure relax) before quarrying was done.
>drill holes knock intervening areas out with a chisel.
Ya, they did sometimes quarry and carve using a technique kind of like this.

No, but one of those images you referred to in another's post is from Dunn (2006) which in some ways does. That would be the image with all the numbers and lines on it.......

There is no geological regionally consistent evidence of that...... at all.
