Looks like Everhard
is a leader in screen tools and mentions an offset fork.
"Everhard Products is a USA manufacturer, fabricating and assembling all its screen rollers at its Ohio facility. We were the first and only manufacturer to incorporate ergonomic improvements into our screen rollers by adding the cushion-grip sleeve, the offset fork, and now the soft grip, plastic handle. Our relationship with our customers and our engineering capability allow us to develop and produce special rollers that match the screen industry's needs"
From the pics it looks like the wheel may be offset slightly to one side - enough to enable you to work the spline - not sure?? Also might be worth a call to see if they have / can provide more of an offset? Seems like you should be able to work w/ the tool at a slight angle and still put some force on the spline.
Second possibility - Phifer Screen Mouse
- seriously not a computer tool - this one is for window screens - video shows vertical use but may have enough of a grip to lay it flat and still exert some pressure on the spline in your situation
