S90V 'Coarse VS Polished ' Edge Retention Test

I often get asked "which is better... a coarse edge or a polish edge? "

Well the answer is.... there is no right answer!

Steel composition, Heat Treat, (subsequent) HRC, and most importantly YOUR CUTTING NEEDS all play a role in which edge is optimal for which steel.

Today I take s90v... a stainless "10v class " steel and see if it does better with a "coarse" 25 micron.. or "polished" 3 micron edge cutting cardboard.

Is a polished edge optimal?

Will carbides jump out and beat my ass?

Why am I sick again?.... carbide poisoning?

Why is Inthepocket smarter than me?

All this and more!
