Tru-Grit 1D、2D、3D、4D、4D、5D、6D、7D

The USA made Tru-Grit flashlight, produced in the early 1970s (though some sources suggest it may have been made in the late 1970s to early 1980s), is conceptually based on Kel-Lite but is not identical. Its body is very rugged and robust, possibly making it one of the thickest aluminum flashlights available, surpassing models like Kel-Lite, and it is nearly indestructible.

The structure is simple, with each section easily detachable, allowing it to be configured as 1D, 2D, 3D, 4D, 5D, 6D, 7D, or even longer. The first section connects the neck of the head to the body. Some believe this flashlight is machined from a solid aluminum rod rather than typical hollow aluminum tubing. The knurling on the body is very deep and aggressive, making it nearly impossible to slip from your grip.
