Iroko is a timber often chosen in place of teak and workable with hand or machine tools, although its interlocked grain can tear.
Why it is chosen
Iroko is used as a substitute for teak when a similar role is needed. Base the choice on the actual board and the job rather than assuming that the two timbers behave identically.
Working the grain
Iroko can be cut with hand tools or machines. Interlocked grain means the fibres change direction through the board; a cutting edge can lift those fibres instead of slicing them cleanly. Take controlled cuts and inspect the surface as you work, especially where the finish will remain visible.
