Noodler's Ink is a small American company run by Nathan Tardif in Southern Massachusetts, USA. The name Noodler's comes from a technique of catching catfish by hand. Noodling involves wading into the water and feeling around for small crevasses and catching the catfish who have backed themselves inside by holding onto the outside edges of their open mouth.

Nathan says it is the ultimate battle between man and beast and your bank balance and social standing have no bearing on your ability. The catfish can be seen on all the ink bottles and packaging.
