Roland,
To me it seems to be based off of the 897UH pattern. Oh, and you are dead on with the "little knife collectors" comment. I was on the couch opening the mail yesterday with my old 8OT and my three year old wanted to hold the blue one. I handed it to her, closed of course, then she wanted my old timer too. I closed it and handed it over to her and you would have thought she won the lottery. Grinning from ear to ear she clutched one in each hand and I had to nearly pry them away from her. Oh yeah, her time is coming!
