I have had my set of ginghers for so many years and they are still razor sharp. All of them are wonderful.
The other ones I have and love are the mundial snips. They have been around more years than I can count and work great!
One thing I will say is I never leave them where someone can use them for anything but for material and sewing.
I have a pair of fisker's spring type for paper cutting. They are very nice to do that with.
