Tricone Bits Shelf Life.

Due to the war in Yemen, the Drilling Operation was suspended in April 2015; as result of that,  we have a good amount of 17.1/2", 12.1/4", 8.1/2" and 6" tricone bits (major brands) in the warehouse, most of them were purchased between 2010 and 2015. I am looking for comments and recommendations regarding the use of these bits exceeding the published manufacture's shelf life. I am aware of the potential risks published by manufactures, however, I would like to have experience based comments and recommendations from the community.
Most of these bits were the latest generation at the time with features to drill tough and abrasive formations
