Help requested - identification of WW1 German penknife

[wm5806]

Please forgive me if this is as common as muck - my main collecting interest is not in militaria and this is something my grandfather gave me many years ago.

 

It's a penknife which, according to the blade, was made by 'FW Backhaus, Ohligs, Solingen.'  The handle has a printed design covered by perspex (now quite yellowed) with I think Kaiser Wilhelm on one side and someone else on the other one.  I expect that it was a Christmas gift in a similar manner to the chocolate issued to British troops, but any information anyone might generously offer would be much appreciated.

 

With thanks, Richard
