Benchmade 4170BK Auto Fact is an effective spring knife that combines the style of Italian stiletto with the functionality of an edc knife and the reliability of tactical knives.
American tool steel
The knife has a slim 100 mm long blade , made of elite CPM-S90V stainless steel , which is subjected to hardening to a hardness of 59-61 HRC, optimal for EDC knives. CPM-S90V is a luxury stainless steel with a very high content of vanadium and carbon, which makes the blade extremely retention, very resistant to abrasion and corrosion. When choosing a hard steel knife, you should get a diamond sharpener, as sharpening with a standard ceramic whetstone can be very laborious and ineffective.
