Sorry but no idea the difference between those kits.
As far as PE stuff. Good sharp blade for cutting. For folding I use a steel rule to hold a piece down, if it has a long fold to make, and fold withe a utilty knife blade. Otherwise I use broad tipped tweezers to hold the piece at the fold line. This brings me to tweezers. I use 2... a broad flat set and a pointy one for only the teeny weenie parts. Optivisor is very useful, especially at my age, to see what you are doing. Gap filling CA glue that will give you a little working time then CA accelerator to get the glue to set in an instant when ready.
This brings me to a tool that I can not do PE without. I actually use this all the time now when using CA glue, not just for PE
This is a sewing needle with the end of the eye ground off making a tiny little fork. Mounted in a wood dowel, or in this case, the end of an artist brush handle. It is used to pick up a tiny drop of CA accelerator from a small jar. When gluing the really small pieces that blast of accelerator form the pump bottle is a waste and gets all over the place.
After cutting the PE from the fret and getting cleaned up and ready to glue… hold it with tweezers and just touch it to a drop of CA on a piece of scrap or apply a tiny drop of glue with a toothpick. Hold it in place where it is to be glued and just touch with the accelerator tool.
