The Dalbergia wood commonly known as "Cocobolo" is a dense and prized hardwood, primarily harvested for its heartwood. This heartwood typically displays a rich orange or reddish-brown hue, often featuring an irregular and dark grain pattern. In contrast, the unused sapwood is a pale yellowish tone, sharply demarcated from the darker heartwood. Once cut, the heartwood undergoes a noticeable color transformation over time.
Cocobolo possesses a smooth, oily surface that resists moisture and can be polished to a high sheen. Due to these properties, it’s frequently used for crafting pistol grips and knife handles. It’s incredibly durable, lightweight, and easy to work with, producing crisp sounds when struck. However, its oily nature makes it incompatible with certain glues and can interfere with the drying process of some paints.
On a microscopic level, Cocobolo exhibits loose porous structures. Growth rings are clearly visible, with the heartwood’s fresh cut displaying shades ranging from dark reddish-brown to deep orange-brown, occasionally interlaced with black streaks. The vessel pores are large enough to be seen without magnification, averaging around 139 micrometers in chordal diameter, with counts ranging from 1 to 12 per square millimeter. The axial parenchyma is prominent under a lens, predominantly paratracheal and arranged in star-like clusters, thin lines (usually 1-5 cells wide), and occasional reticulate patterns. The wood fibers have thick walls, while the rays are clearly visible (appearing orange on fresh cuts). These rays form continuous columns, though their characteristic wavy patterns aren’t always apparent. The freshly cut surface has a spicy aroma, and the grain structure is fine, either straight or slightly interlocked. The air-dry density ranges between 0.98 to 1.22 g/cm³, making it one of the heavier woods.
Despite its challenges with adhesives and paints, Cocobolo remains highly valued for its aesthetic appeal and durability. Its unique combination of colors and textures makes it ideal for artistic woodworking projects. However, due to its rarity and the environmental concerns surrounding its harvest, sourcing Cocobolo responsibly is increasingly important.

Hand Tools
Hand tools are manual devices designed to assist with various tasks and projects. They are typically operated by hand and do not require any external power source. Hand tools come in a wide range of shapes, sizes, and functions, and they are commonly used in industries such as construction, woodworking, automotive, plumbing, electrical work, and more. Here are some common types of hand tools:
1. Screwdriver: Used for driving or removing screws, screwdrivers come in different sizes and types, including flathead and Phillips head.
2. Hammer: A tool with a weighted head and a handle, hammers are used for driving nails, breaking objects apart, or shaping materials.
3. Pliers: Pliers are versatile tools used for gripping, bending, cutting, or holding objects. They come in various types such as needle-nose, lineman, and adjustable pliers.
