The best scissor on the market today for school & home use is Fiskars! They will cost you a little more up front(not terrible if you find them on sale...like at the start of the school year), but the cost will be made up through their longevity! I am using some of the same Fiskars that were here when I started teaching at Tulip Grove for the '01-'02 school year!! That's pretty good when you think of how hard kids are on things! I also use Fiskars cutting tools in my scrap booking!! I teach Scrap booking 101 & Scrap Social at Jo-Ann Fabrics in Mt. Juliet, TN...and will often recommend the scrap booking/crafting cutting tools that Fiskars has there. If you wait for Jo-Ann's sales....or the coupons you can find in the paper/on-line....it is a wonderful investment!
http://www.fiskars.com/ will provide you more information on these fine cutting tools. The website also provides great information for TEACHERS, CRAFTERS, and GARDENERS!!! CHECK IT OUT!!!
