Schrade did do knives in stag and bone, though not usually standard production knives (after the early 1960's). I have a 34OT with bone handles and sterling silver bolsters. One of the 897UH knives in my picture above is burnt stag. Another is jigged bone.
The hinge top boxes were relatively short lived. I have very early issue 15OT and 165OT knives in those boxes from 1964 and 1966. Earlier OT and UH hinged boxes were wood and are seen in the late 1950's with the intro of the first Old Timers, the 2OT, 8OT, etc. Boxes became slip top for a while then fold down except in the case of some special editions like the GDOT series and some commemoratives.
The failure of the company to survive goes much deeper than product offerings, IMHO. Like with Camillus, the sister company. It had to do with the loss of visionary leadership of the founders and the direct management they selected. Camillus went under while offering some of the most innovative, bang-for-the-buck knives in their history. And don't forget that the example CASE has flopped, floundered, been bought and resold several times since owned by the Case family. I believe that if you will talk to Sal, Les and others in the manufacturing relm they will tell you that they are in a constant horse race to keep up quality, introduce new designs and materials, hold down expenses, and forecast a year or two out what the market will want.
