I was at a trade show recently and met Sue from Acme United Corporation. She gave me a demo on the titanium scissors and boy I was impressed! What I like about these scissors first of all they are bright pink... I won't loose them in my studio like my other pairs, but this particular pair have a "Blade Tension Key" so if you are cutting layers of fabric you can adjust the blade tension.
You can cut several layers at a time easily.
