I have a pair of Fiskars from JoAnns. Used my 40% off coupon.
I use them to trim the stabilizer from my machine embroidery.
They stay very sharp. The blade is about 3 inches. I am a lefty and the pair I bought has straight handles so they can be used for leftt or right handed people.
My husband wanted a pair of scissors for work, he is a mechanic, he needed something to cut out gaskets and stuff, he bought a pair of the Fiskars, using another 40% off coupon. He bought a pair with longer blades and he has said they are still very sharp after using and abusing them for several years.
I think his has the long straight handles as well, the ones with the holes in the handles will hurt your thumbs if cutting a heavy product.
