I like my Fiskars tools- I use my brushhook as much as my billhooks (similar but different) and I have a selection of other stuff. Good basics- although I also have my traditional restored stuff too.
I don't have any Fiskars secateurs, but I have found that with any secateurs it's very important to clean and sharpen regularly. Niwaki sharpening stones are ideal as they have a side which is shaped for secateurs blades, plus they do a "crean mate" which is a sap remover. (My budget doesn't stretch to Niwaki secateurs unfortunately.....).
The Fiskars range of scissors is generally good- the classic dressmakers shears and razor scissors are excellent, although I will say that their embroidery scissors are not very good, the Prim Kai ones are way better and a similar price.
Generally though, I think that Fiskars tools are good value for money, pretty bomb proof and tolerant of the level of abuse/neglect they will typically get;
@British Red - I think your video is a fair summary.
