The Tailor model that I saw a picture of was a very straight, simple blade. It appeared to made from the same stock that the model 10's are made from. Being, 1/8" x 1" stainless steel bar stock. It had a very straight cutting edge looking to be about 2 inches or so long and angleing to form an acute and sharp tip. The handle, if you want to call it that, was straight bar stock without contour or form. It looked like a number 11 xacto blade on steroids. The tool was sheathed in a simple leather slip. I would imagine this cutting tool is very popular with professional tailors in the modeling of clothes and hence the name. I think it would be a perfect cutting tool for the backpack or tackle box.
