Ha, I inherited my old man's cantilever box when I started as a labourer. Great things until they slip open when you are stood on them.i spent the first 10 years on the tools using a metal cantilever mechanics tool box , indestructable.
good times long since gone.
Don't really see the appeal of a tote bag. I much prefer a solid box. Have a fatmax structural foam ip rated jobby at the minute. Bloody love it.
