What is PATINA?

The Potomac Antique Tools and Industries Association, Inc. (PATINA) is an educational, tax-exempt organization for people who have an interest in the tools, crafts or manufacturing processes of the past.

Formed in 1977, PATINA is a regional tool club based in the Washington, D.C. area. We have members from 24 states, the District of Columbia and several foreign countries. Antique tool collectors, tool users and people simply seeking knowledge are well represented in PATINA's membership. The annual dues of $15 includes membership for the entire family and they are welcome to participate in all PATINA events. PATINA's original group of about 30 has grown to over 350. Antique tool collectors, tool users and people simply seeking knowledge are well represented in PATINA's membership.

Our mission is to promote and increase knowledge and understanding of the tools and trades practiced by our American ancestors.

Our bimonthly meetings, held at the American Legion Post 270 in McLean, Virginia 22101, generally start with tailgate sales around 9:00 AM, followed by a short tool auction around 12 noon. The presentation by the guest speaker begins after the auction.
