I use a small hack saw to cut the syringes.

We have an orthopedics department and the casting room
has lots of cutting and sawing paraphenalia.  Putting the
syringe in the vise makes cutting a snap. Someone told me
they used sharp scissors, but when I tried it the syringes
cracked.

Maybe we should cut a deal (pun intended) with a syringe
company to manufacture what we need?

I find I most often need the 20cc size.
