How this board opens
A first sweep of the overlap rule down the rows and across the columns settles 198 of the 400 cells, about 50%, which is enough of a skeleton to work outwards from. The most generous opening is row 1, which gives up 20 cells on its own. 11 of the 40 lines are decided outright by their clues, with no room to slide. From there the board finishes on row-and-column logic alone — there is no point where you have to try a cell both ways and see which one breaks. The finished picture fills 94 cells, and the longest unbroken run anywhere in the clues is 8.
About this category
A hammer, a pickaxe, a scythe, a paint roller, a quill and an inkwell, a needle drawing thread, a mortar and pestle, a padlock hanging open. Most of what is on this shelf is an implement, and an implement is nearly always the same two things joined together: a handle and a head. That turns out to matter more for solving than the subject does.
