A friend of mine gave me this piece of Dipteryx panamensis. It is an incredibly dense wood– it measures 29 x 7 x 4 cm and weighs 881 grams. (11.25 x 2.75 x 1.5 inches, 1lb, 15 oz.), and can have a specific gravity up to 1.09. I will most likely never get another example of this wood, I think it is now banned for export.
I considered making tool handles or something else out of this, then realized there was nothing I could do to improve– it is perfect the way it is. Any shaping or transformation would only diminish it.

What to do with such a rare piece of wood: Making „boats, bridges, flooring, general construction, mine props, railroad ties, tool handles, vehicle platforms”. More infos here: http://tinyurl.com/n23cka [Elsevier’s dictionary of trees]
One of my friends restored a veteran car Ford A Type Cabriolet 4 seats especially built for Costa Rica’s Chief of General Staff in 1935. The bottom was original carpenter work made of „Tonka-Wood” and 1998 in best condition.
