Ipe Hardwood Lumber from Woodworkers Source

ipe hardwood lumber 450x4501 wood flooring cladding

This is one strong, tough, and resilient wood. Ipe’s naturally durable and weather resistant so it’s fantastic in outdoor projects. Moderately difficult to work especially with hand tools; has a blunting effect on cutting edges, however Ipe finishes smoothly except where grain is very roey. The rich dark color makes great accents.
