Stapler Model WITH Subdivision Surfaces 

I thoroughly recommend adjusting your theme so the Face Orientation overlay is fully transparent front-facing, and a pleasant tint, backfacing. That way you can leave it switched on all the time while modelling, making it easier to see what you're doing, and to spot inconsistent normals straight away. I honestly don't know why the default overlay is in such vicious colours.

Fantastic tut! Thanks for that well explained workflow!

If you press the e key when doing a loop cut, it makes the cut perfectly even to one of the two edge loops it’s in between. The f key changes which edge loop it’s parallel to. There’s no need to inset.

Great tutorial! I always though that we need to use quads every time, but this proves me wrong

Thank you, I learned a lot of things from this video.

Fantastic Christopher, thank you
