It is not recommended that you over-sharpen your increment borer (this could make the bit brittle and prone to breaking), you should only sharpen it if it needs to be sharpened. Remember: Clean your increment borer frequently (using a gun cleaning kit) and apply WD-40 to preve..

David Stahle travels to ancient forests around the world, collecting tree rings to learn more about major climate and historical events dating back hundreds and thousands of years. With help from the National Science Foundation, he uses Dendrochronology, or tree-ring dating, to get a snapshot of climate change over time. Stahle can also determine things like the socioeconomic impact of droughts...

Ancient Trees Reveal Environmental Histories from Lamont Doherty on Vimeo. Evidence from old-growth trees and ancient timbers recov­ered from homes and barns in the eastern U.S. and Hudson Valley region suggests that the climate and ecology of the previous four centuries may not have been as temperate as once thought. Using dendrochronology, or tree ring analysis, researchers at Lamont-Doherty n..
