Aptly named for its purplish heartwood, purpleheart has become a favorite for woodworkers looking for both color and strength. These purpleheart knife blanks provide excellent strength, rot resistance, and a solid feel in your hand. The color is dull when freshly cut, brightens over a period of days to a deep purple, and darkens to a purplish brown in the long term. Color changes can be slowed with the use of UV-inhibiting finishes. Use sharp tools and take care not to overheat cutters.
