There used to be a big carpet factory in the area. I knew a lot of fellows who worked there. The workers carried a pouch with some peculiar scissors and these types of knives. This particular one probably didn't come from there. The issue knives at this place had green painted handles and were marked John Primble but were otherwise the same. The blades always dished out in the middle. Carpets are very abrasive. I might have a pair of the scissors somewhere? Best wishes. G
