PRE-WWII - The famous, and quite rare "Pat. Pend." style of the pre-war vintage National finger pick- thick and heavy, this design started the trend for finger pick makers to put holes in the band for better grip and to minimize problems with perspiration. This style was made after the patent application was filed in 1928 through at least the mid 1930's. A 1940 National Dobro catalog shows the Pat. Pend. style in an illustration, priced at 10 cents each. The metal used was high-quality German silver, also called nickel silver, which is an alloy of nickel, copper, and zinc. These are the most highly regarded finger picks ever made. They are extremely comfortable and have a spoon-shaped blade.
