Benchmade 4170BK Auto Fact


The 417 Fact® re-imagined the classic Italian Stiletto knife as a contemporary EDC and Tactical tool. Now it's been taken one step further with the new 4170BK Auto Fact®. Featuring aerospace aluminum handle scales with a sleek carbon fiber inlay, the addition of the Auto AXIS® mechanism connects this modern-day folder to its traditional switchblade roots. A black DLC coated blade, made of premium S90V super steel, ensures phenomenal edge retention for prolonged life and low maintenance, making the Auto Fact® a perfect choice for enthusiast and super-spy alike.
