Welcome to PATINA


The next bi-monthly meeting will be held at at the American Legion Hall in McLean on Sunday, July 10.

Our flexible schedule is tool swap starting around 8:30 until 11. Mini-auction from 11-12:15, with the presentation to follow.

Special Notice!!! The family of Marty Knudslien, one of our earliest members, has asked the club to sell his wooden molding plane collection of 450 planes, and has also requested that the club offer them to PATINA members at a reasonable price so they go to someone that appreciates them as much as Marty did.

There will be a significant number of these planes at the July 10th meeting in McLean. Please inquire at the tailgating segment, or inside the facility before the mini-auction.

As always, please reserve parking in the upper lot for tailgaters, and if you are simply planning on attending the tailgate and meeting park in the lower lot.

2022 membership dues are being collected now!

Please remember to pay your dues ($15) so we can fund our annual event in October, as well as the educational programs that we conduct at local meetings.

Send check made to PATINA or use paypal at patinatools45@gmail.com

If you are unable to attend a meeting and need to renew your membership, checks can be mailed to Membership Director:

Mary Anne Graham
P. O. Box 211
Round Hill, VA 20142

Please support the club so events can continue. Thank you!

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 $15.00 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.
Our mission is to promote and increase knowledge and understanding of the tools and trades practiced by our American ancestors.

The PATINA website was created to provide regular announcements of upcoming meetings and auctions, reports on past meetings, reviews of relevant publications, and notices of other tool-related events. As an educational organization, PATINA is often invited to stage exhibits and demonstrations for local and national groups that express an interest in early tools and trades.


PATINA is sad to report the passing of two-time President John Williams on Sunday, April 24th. Our dear friend John always had a smile on his face and promoted tool collecting with enthusiasm. He was a passionate plane collector with a special interest in Baltimore planes. He was working on a comprehensive update to the Dick Hay treatise on Baltimore toolmakers.

John was eager to share and support the passion for tools in so many ways. He will be missed.
