Hi Sam, the tool was purpose built from an old 8 mm Ajax bolt and some square section steel rod. The guy that I borrowed it off made it specifically for his Suzuki Stinger T125 seat trim. It worked perfectly for me. I gently tapped the bolt part along the folded rim of the trim and it just magically pushed the part back into place. There was quite a bit of dickering around of course but the tool worked very well.
