The knife steel.
S30v..
.
this has been the premier folding knife steel for a while and for good reason. It gets crazy sharp.
"All steels can be equally sharp if sharpened"
No.
Some steels just take a more keen edge then most, s30v is that steel.
Its highy alloyed which although it doesn't take a mirror polish well its powdered metallurgy forms a very unifomed structure that rips through materials.

This steel is a great baseline for what sharp knives are.
But like all fixed blade guys know. Its about toughness.
The Benchmade 162 took a hit form critics for its steel selection.
"Its not carbon steel, it won't make sparks with chert or flint( not to be confused with ferro rods)
First off a knifes primary purpose is to cut. While its fun to daydream about using a knife and a rock to make a fire, Frontiersman (who depended on flint and steel) used carbon strikers, not knives to make sparks.
Most Carbon blades have coatings and high speed tool steels are also sometimes semi stainless and don't work.
Making a fire with a knife is cool but should never be a deal breaker.
Another complaint.
" S30v is too hard to sharpen and too brittle."
Yes S30v can be more difficult to sharpen (more time to grind) then carbon steel
Keep in mind however heat treatment changes everything.
I'm very impressed with Benchmades heat treat. This s30v is tough not just hard. I've used s30v on a few folders including my Manix 2. While impressive, (if not careful)the blade will chip where other would roll and strop back.
I knicked the blade on the spine of a handmade file knife I was carving the handle for.

I was pissed. On my Manix it would have require some grind on the diamond stones. However upon inspection of the 162, it was a roll(.5mm) I was stoked but skeptical. Most rolls turn into chips when sharpened but with some passes on my work sharp ceramic rod
it bent back to shape. Excellent steel for outdoor use.
