Blaisdell produces first square-cornered windproof lighter with no diagonal lines on the corners. This model is 2-7/16 inches tall, 1/4 inch taller than the now standard Zippo lighter. The Insert is also approximately 1/4 inch taller.The Zippo have eight holes ,located on each side of the chimney and a three-barrel hinge outside of the case.

Diagonal lines are added to the 1932 " tall model",for the most part in 1933 , which is still 1/4 inch taller. Both the case and the insert are shortened during 1933.

During 1934 the 1/4 inch shorter units continue to be produced with the 3 barrel hinge plates still on the outside of the case. Blaisdell applies for the Zippo patent on May 17, 1934, after test marketing the product for two years.

Metallique specialty advertising begins with Kendall Oil's order of 500 lighters in 1935.

Two different models are produced.The first model has four-barrel hinge with the plates still located on the outside of the case. The second model has a four- barrel hinge as well, but the plates are moved to the inside of the case. The case is still the square-case variety. The patent #2032695 was issued March 3, 1936 , so lighters manufactured only late in 1936 had the patent.

Production begins on the 1st model Barcroft table lighter. This model is only produced during 1939 and 1940.

The brass drawn case with no metal clips inside the lid makes its entrance. It has one piece extended from the hinge that supplants the metal clips. This variation with the flat bottom is only produced in 1940 and 1941. Lighters produced today are made the same way with the extended hinge.

Zippo fabricates cases made of nickel-silver alloy between 1946 and 1947. These new Zippo lighters featured a canned bottom and an overall rounded look , still seen on current models. The 1946 model has a case that is 1/32 of an inch  taller than the cases today. It has a three-barrel hinge ( the center barrel is longer than the sides) and a 14 hole chimney. The teeth of the flintwheel are horizontal. In Oktober 1946 Zippo restarted production of lighters with an improved flint wheel and cam. The case material of this late 1946 was still nickel silver , but now its chrome plated.

The case is made of chrome plated nickel-silver, and it has the same size like models today.The insert has a 16 hole chimney and the flintwheel has slash teeth.
