Metal types& coats.

[Norwegians love Buck]

Would anyone be willing to take the time, and explain the difference between 420HC Satin, and S30V satin?

What is Chipflint? What's the difference between 420HC chipflint, and S30v black Cerakote.

My guess is that it's just the black coat left on metal after it's cooled down from being in the forge, but I was hoping to get a more detailed explanation.

Does it make a difference using the knife if the blade has the groove or doesn't have it? What is the purpose of the grooves besides adding to it's appearance?

"Satin" is a degree of polishing. It's a finish
S30V and 420HC are two different stainless steel alloys. They are significantly different in the edge retention.

"Chipflint" is a "finish" of the steel which is supposed to make the steel look rough and resemble chipped flint prehistoric knives. 420HC is the alloy.

"Cerakote" is a coating.

Perhaps it gives you a starting point.

A "Blood Groove" which is more appropriately called a "Fuller" is designed to lighten the blade and allow for a more neutrally balanced hand feel at best, or sheer aesthetics at worst.

Sometimes they can make or break a knife, and some of the time folks don't care either way about them. That being said, I think it would be accurate to say that most folks on this site prefer to not have one on a knife.
