I have my grandmother's Wiss scissors. I have no idea how old they are, Granny died 21 years ago at the age of 82 and she sewed all her adult life. They are wonderful scissors. I also have a 25+ year old pair of Fiskars that work well, but do not hold an edge as long as the Wiss.
I used the Fiskars for synthetics, interfacing batting etc.
I also bought two pair of scissors at Staples for paper and other projects. They are incredibly sharp and were about $15.00 for both.
