Hi -

I admit to trying to cut the 20CC syringe with a scalpel - didn't cut myself -
but took FOREVER - so scrap that one.

Then tried a knife - worked much better - but didn't feel like doing 100  of
them.

Sent several boxes down to the carpentry shop in the hospital - they cut them on
a lathe I think - nice smooth surface but oily - So - I had the syringes washed
in the central supply  - and they  work like a charm.  Very cheap - easy to use.
If you are in a hospital you might wish to try this route.  bon chance,  Kim
