This is a style of knife I've never seen before. The design provides for very exact depth-of-cut adjustment.
As with many utility knives, the handle is a spare blades storage compartment; it opens up like so.
On the handle it says, "(KUTTO) PAT'D 1-10-40[1] MFG'D BY THE MODERN SPEC. CO., 4140 W. HARRISON ST., CHICAGO, ILL."
That outfit still exists, but their address in Chicago has changed. They still make a very similar knife, but I don't see this exact style in their product list.
Into the spare tools drawer with it.

[1] That date was a bit indistinct; I may not have transcribed it quite correctly.
