I came here to comment on G-clamp. I wonder where the author is from. I started building things as a kid, I've worked for quite a few contractors over the decades, I've sold some of my wooden creations and met many skilled people with beautiful shops in the US and Australia and have never ever once heard G-clamp.
I am British but also French and lived in many different places. I'm just confused. I imagine someone called it a G clamp in front of me at some point and I just started calling it that.
I'm also British (SW) without the French or many different places - 'cramps' is new to me as far as I can remember. I'd call it a G clamp, and so does Screwfix, fwiw.
G-clamp makes total sense, I'm just curious!!
