Why Choose Cumaru?
A strong, tough, resilient wood that fits the bill for a dark or medium dark project. Good resistance to insect attack and weather. Cumaru is extraordinarily stable and also provides a moderate blunting effect on cutters and blades. Accepts varnish satisfactorily, and will make some very robust furniture.
Get your hands on a wood you've never tried before! It's simple. Samples are milled on all sides to the standard size of 1/2'' X 3'' X 6'', as determined by The International Wood Collectors Society, and include the shipping cost within the 48 U.S. Each one is labeled with the botanical and common names. Use these to test finishes and stains, to compare color and grain characteristics, etc.

What Does The Janka Hardness Rating Mean?
The Janka hardness test is the international standard for measuring the resistance of a sample of wood to denting and wear.
It's expressed in psi, or pounds-per-square-inch. The test measures the pressure required to embed an 11.28mm (.444 in) diameter steel ball into wood to half the ball's diameter. The measurement was developed to determine whether a species is suitable for use as flooring; however, we include it here and compare it to the rating of red oak to help you make a buying choice.
There is a difference between hardness and being difficult to work with. Generally speaking, the harder the wood the easier it is to finish and polish. Harder woods create good, solid long-lasting joinery in furniture.
The hardness of wood varies with the direction of the wood grain, and varies from piece to piece. So a Janka rating is an average of numerous tests performed on all directions and numerous pieces. Use the Janka hardness rating as guide, not a definitive answer.
