Office Cutting Blade - Slim Tanto Style

This is an Office Cutting device.
I've searched for something like this, but doesn't find anithing exclusevelly for this kind of blade.

In Brazil we call it Stillete Blade.
Generally has an mechanical system to supply the blade as soon it became blind.
But i've need to stand still to cut tapes from carton boxes and remove some burr from prints.

Parts needed to mont one.

1 x 18mm Office Cutting Blade
2 x 6 x 1,75mm rare earth magnets
11 x Flat head thread screw 2,2 x 6,5 mm
