People keep asking if mirror polishing an edge makes it sharp... - The Practical Blade

Cleaning / Lubrication:

Assembly / Disassembly (Drivers / Bits):
I STAND BY WIHA! WIHA provides hardened steel bits - and for those of you who are new to this - hardened steel bits are critical to ensure you don't strip bits and get in a nasty situation where your knife is half-disassembled and your bit no longer works! Do NOT buy those cheap 50-piece kits that come with "everything" for like $10. They will not last you, you will regret it.

Blade Sharpening / Polishing:
The KME sharpening kit might seem a bit pricey at first, but in my opinion it is 1) Much more affordable that its competitors, 2) Insanely simple to use, and 3) A small price to pay for nearly-indefinite self-sharpening for all of your knives. You can also create your own "stones" using balsa wood and diamond compound to give yourself a mirror edge at a fraction of the KME polishing accessories prices.

Good sharpening makes it sharp. Polish helps remove a small amount of drag on a blade that size.*

A polish is nice but I prefer a toothy edge for my edc’s

Damn that’s so bloody sharp!.
I have a Hapstone knife sharpening system with the best diamond stones. I sharpened a sandvik 12C28N to 2000# with a strop and it couldn’t even cut paper like how YouTube’rs sharpen their blade Like a Wilkinson razor 🪒 blade .
It’ll cut in some places like a razor and other places where tearing the paper and I make sure I get burs all the way through before turning blade in device around to sharpen.
It beats the hell out of me and that’s why when I see videos like this I take my hat off to whoever sharpened the blades to perfection.
The Hapstone is said to be better than the TS PROF KO3 sharpening system by many YouTubers that are involved in the sharpening videos (which was the god of all sharpeners )
I hope I can at least get my knives sharp like yours bro it’s just magic to my eyes seeing it cut paper like that

I agree. You can’t get get a spyderco’s
Maxamet steel to stay sharp with a polished edge but leave it on 300# and watch the difference. Superior performance.

I remember when I saw this video and couldn’t do this and now I’m able to split hairs with a mirror or non mirror
