The KNAFS Bit Driver is a purpose-built EDC Torx driver for pocket knife maintenance and field repairs.

No dumping bits out of a handle to find the right one.The aluminum body is covered in jimping and knurling for grip. The end cap is aluminum with an internal bearing for clean rotation while driving. At 4" long and 1.3 oz, it lives in your pocket without bulk and handles most knife hardware on the market.Specs Length: 4" (102mm) Diameter: 0.5" (13mm) Weight: 1.3 oz (36g) Body: 6061 aluminum Bits: Wiha Torx T6 x 28mm, T8 x 28mm, T10 x 28mm Retention: O-rings (4 included) Designed in Utah, USA Ships fast from the US.
