I use a Stainless Spatula that's made for Rod Building Epoxy. I got both of mine from AcidRod.com. I buy from AcidRod whenever possible, and stay away from most other retailers of Rod Building Components. AcidRod does business right. My spatulas fit in the hand well, they're stiff, fairly fine-tipped, and machined so they're not sharp anywhere so they don't scratch...and about $3 each. I also have, from AcidRod, a Marbling Tool that's made for Marbling Pigment and Work. Pointed tip on one end, small Rounded tip on the other end. Very nice little tool, also $3.
