I've read the sharpening and polishing sticky at the top of this section and while it does look like exactly what I need and within my ability, one thing the guy said in the videos bothers me. He said the sandpaper was a good way to clean a katana blade and get rid of a fake hamon you don't like.
Does his method of sharpening affect natural hamons in the same fashion? I would not want to damage any hamon while sharpening my sword and I am concerned that will happen if I use this method on a sword with a natural hamon.
Am I being paranoid or justly cautious?If there is a proper method for sharpening a blade with a natural hamon, please enlighten me in this matter.

I'm not 100% sure, but I don't think a true "Hamon" will be harmed by polishing, or sharpening, I have not done it, but from what I have been reading, you may have to "re-etch" it to bring it back out, but a true hamon is all the way through the blade.
like I said I'm just a new guy, and could be wrong. you might see what some other people say, before you dive in.

Yeah, the hamon should be fine... it may get invisible at lower grits of polishing/sharpening, and you may have to polish/etch it back out, but like he said, a 'true' hamon goes all the way through the blade. Now, if the blade was laminated, that COULD potentially be a problem, but laminated blades are pretty rare these days... if you don't KNOW that your katana is laminated construction, I would bet cash it's not. DEFINITELY not if it's sub $300... Anywaym, take a look at Tom K's (Ianflaer on youtube)'s sharpening videos... he has a great tutorial. Som, to sumerize, sharpening and/or polishing will NOT destroy/damage a true hamon, unless there's some freaky detail I'm not aware of. The worst that could happen (assuming you sharpen the blade correctly) is that the hamon 'dissapears', but that is easily reversible. ;D Hope this helps! -Slayer

Technically the hamon is already in the blade but poor polish could obscure the hamon. If this is your first time polishing (and if it is a monosteel), my advice is to get yourself a cheap DH blade (from $80 Musashi for instance) and practice polishing from there before starting on your expensive pieces. If it is a nihonto, don't do anything to the blade, at all. Ask a professional sword polisher to see whether it is worth the cost to polish it. Let them handle it if it is worth the money. An amateur sword polish could easily ruin the blade and its value. Edit: Yes you could easily remove a fake wire-brush hamon with some sandpaper. For a Hanwei acid etch hamon, there is a sticky at Japanese sword section that elaborates on how to remove that cloudy hamon with some mother's mag. Highly recommended reading if you are thinking of removing Hanwei hamon. No sandpaper necessary if done right.

You COULD actually damage it if you use something electric. I can't see anything in the tutorial so I don't know if he uses anything electric. But heat buildup could ruin the temper. Since it is differentially hardened, it would be a shame to soften up the harder blade edge.
Just sandpaper? No. Won't do a thing. Uless of course you push really hard and rub it really fast, but that should burn your hand before you could do too much damage.
