I have one gripe about scissors. I don't like the handles. You used to be able to buy grips that fit inside to make the openings smaller and less slippery if scissors were all metal. I have long double-jointed fingers and the scissors slide terribly. I've been using the Fiskars that squeeze so they stay put. Havel does use these inserts on the smaller scissors.
I have one old pair of Gingher that I haven't been using just for this reason.
The older scissors were better in some respects. I gave a family member a pair of Singers twenty years ago to cut his hair with. I didn't like them. Just out of curiosity I ran them through the Fiskars Sharpener and they cut fabric very well.
So it must be the metal alloy or manufacture thereof they used long ago.
