Lithco Plastic Ink Knives are molded from chemically-resistant polypropylene — a durable, solvent-safe alternative to metal and wood ink knives. This set of four (one each in red, blue, yellow, and black) is designed to fit into one-pound ink cans. They won't scratch nylon or Teflon™ ink feed systems, resist solvent absorption, and leave no crevices to trap ink residue or cause color contamination.

Frequently asked questions
Why use plastic ink knives instead of metal or wood?
Polypropylene knives won't scratch nylon or Teflon™ ink feed systems, rollers, or plastic adjustment keys the way metal can. And unlike wood, they don't absorb solvents or develop crevices that trap old ink — which prevents color contamination between jobs.
What are the four colors for?
The set includes red, blue, yellow, and black knives so you can dedicate a knife to a color family and avoid cross-contaminating inks. (Actual colors may vary.)
Which size should I choose?
Small and Regular suit precise work and smaller cans; Medium and Large are especially effective for removing excess ink from fountains. The knives are sized to fit one-pound ink cans.
How do you clean them?
Wipe down with solvent and shop towels. Because the polypropylene doesn't absorb solvent or trap ink, cleanup is quick and turnaround between colors is fast.
