Marblewood’s heartwood is a yellow to golden brown, with irregular brown, purple, or black streaks. The sapwood is paler than heartwood and is a solid yellowish color lacking contrasting streaks, usually up to about 1" thick. The high contrast between the golden body and the much darker streaks give it an appearance somewhat similar to natural marble, hence the common name of “Marblewood” for this species. Marblewood’s overall appearance is very similar to zebrawood, though marblewood tends to have a slightly finer texture. Marblewood comes from Northeastern South America.
The awl's shaft is hand-forged and twisted from 01 steel with a Rockwell hardness of 62. The tip is sharpened for use in starting and boring holes which the square shank then widens through repeated twisting.
The 1 3/4" handle is sized to fit comfortably in the user's hand and allow application of a generous amount of pressure when twisting the awl. The finger grip is positioned in precisely the right place to enable a firm grip in use.
