Guys,
Hit up the fast food joints for one of their HD plastic straws and re-purpose it when you're done slurping down a slushy or a shake.
Use a long enough section to cover the point of the scissors. If you want to really get into it, heat seal the end of the straw.
I'm pretty sure the thin plastic will be lighter than the silicone tubing.
Also you can avoid the "IHateSupportingtheWaltonsmart" stigma if you so desire. ;-)
Party On,
Newton
BTW my scissors arrived today and they look like this…

…and yes they are not what I ordered. ;-?
Here is the good news. I'm keeping them because the finger loops are large enough for my fat fingers. They were advertised as 1.5 oz per pair. They actually weigh 30 grams or 1.05 oz. I'm pretty sure that the larger finger looped version would be heavier.
They seem to do their job (cut) very well. They aren't the lightest option but I'm a gearhead gadget freak and I like the way that they fold up and stow the points safely away.
Newton ;-)
