Did you cut it yourself?
I did.

I don't know why you guys are going out of your way to copy exactly how much from the edges the grips reach. Multiple screen shots have shown that the lengths vary from hilt to hilt, which at least makes it plausible that they were all cut to approximations without any intention of cutting them to any specific length to achieve a particular look apart from just making sure that they're not too long or too short. If there were as many hilts available for ANH and ESB, we'd probably see exactly the same.
By the way, I've come to understand that the ANH hero has the grip ends cut to a slant whereas the ESB has perpendicular corners. Yet, there are also grips for the ANH version that come with rounded ends. Was it the case that the ANH hero is shown with both grip versions?
For sure, I'm just doing it this way because it looks about right to what we see on screen so far.
