Griffin MKIII Bit Driver - Satin Brass

The Griffin MKIII bit driver in satin brass hits a sweet spot between the titanium builds and the copper options. Brass carries a similar weight and density to copper but with a warmer, golden tone that patinas differently — expect it to shift toward darker honey and brown tones over time rather than the green verdigris you get from copper. The satin finish starts clean and polished, giving you a front-row seat to the entire patina journey. If you like watching your gear develop its own identity through use, brass is one of the most rewarding materials to carry.

Wiha Torx Bits Ready to Work

Four Wiha Torx bits come standard — T6, T7, T8, and T9. The same sizes you'll reach for when tearing down a folder for cleaning, swapping a clip, or adjusting a pivot. Any standard 1/4-inch hex bit fits the magnetic holder, keeping the MKIII versatile beyond knife work. The 608 ceramic bearing top cap spins without resistance, and the milled grip pattern cuts deep enough into the brass to maintain solid control even as the surface develops patina. Measures 4.125 inches long at 0.75 inches in diameter.

Solid Brass, Machined in Canada

Machined from solid brass bar stock and finished in Canada. The body screws apart to access internal storage for three additional 1/4-inch hex shank bits. Each driver ships with a branded pouch with Velcro patch, cleaning cloth, stickers, and a signed and dated certificate of authenticity.
