Beautiful box JJ... gotta admit that the boxes usually supplied are either crappy or cardboard.
I never got fancy with custom made handles... call it lazy or lack of imagination... SWMBO calls it talent (errr, lack thereof). However, I do have an aversion to handles on top... they stop stacking, and bigger ones may inhibit drawer closure, ... some may appreciate why I'm now over making boxes for tools.
I've gone "streamline" stackable, though they may be side and length "clumsy".
I only buy Fe$tool for the stackable 'tainers! For pottzy's eyes only, 'tainers are great for wrapping Bos¢h in "cotton wool paper", protecting them from getting screwed!
If your first cut is too short... Take the second cut from the longer end... LBD
