A 1 x 6 x 8 gridfinity bin, that is designed to hold my 2 cheese knives, the blade cutout is 3mm x 112mm and 40mm deep, the handle cut out area is 36mm x 110mm x 30mm deep. If you have a cheese knife that has the curved-double pointy end, put it in upside down so it's not sticking out the top of the bin.
