Sawist is a person who plays the musical saw. It has been used in print in the publication 'Saw Players News'.
A long debate between musical saw players about whether to call themselves 'sawists' (like pianists, violinists, etc.) or 'sawyers' (like drummers) was settled by Natalia 'Saw Lady' Paruz at the 6th annual NYC Musical Saw Festival (2008). Since the word 'sawyer' already exists, meaning a person who cuts wood, musical saw players are now called 'sawists'.
That's rather iroquoisy. A few days ago, I posted this picture and talked about it with some Wordie users (for those who don't know what it is, Wordie is the wonderful website that is about to merge with Wordnik).
Wait a moment: iroquoisy, or is it how user SawLady discovered Wordnik?
