Benchmade 4170BK Auto Fact

The Benchmade 4170BK Auto Fact re-imagined the classic Italian Stiletto knife as a contemporary EDC and Tactical tool. 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 spear point blade (premium CPM- S90V super steel) with a black DLC finish, ensures phenomenal edge retention for prolonged life and low maintenance, making the Auto Fact a perfect choice for EDC and Tactical carry.

CPM-S90V Steel: CPM-S90V steel is well known for its wear-resistance. According to Crucible, S90V is used in plastic feedscrews, valve components, nozzles, slitters, cutters, gear pumps, pelletizing equipment, bearings, and other hard use parts. In the knifemaking world, S90V is legendary for its near perfect edge-retention. It is close to impossible to dull a blade made of CPM S90V. That being said, you need the patience of a saint to sharpen it, however infrequent that may be. S90V is in the upper echelon of knifemaking “super steels”, as is evident by the hefty price tag that accompanies the knives to which it adorns.
