Just one more quick question. Does the Mother's Mag leave a protective coat on the blade. I've noticed the oil doesn't stick to the blade like before.

Yep. You can give the blade another good cleaning with the Windex and rubbing alcohol to remove it.

Looks amazing... Just be aware that mothers mag can dull the edge a bit if you repeatedly expose it to the polish. But that looks awesome... Wow... So jealous lol.

I didn't go right to the cutting edge, in the one place I needed to I was very careful. Don't plan to do that again anytime soon either..lol

Very nice job. That has been on my back burner waiting until I needed to resharpen and having time on my hands. Concerning your lack of Windex or other available material to neutralize the vinegar, acetic acid, common baking soda not only works well but is noted for doing so. You take me back to my Chemistry 101 days. I have browned metal, a process similar to but older than bluing, and to stop the effects of the acid I used it. Baking soda is a buffer. That is it will bring an acid or a basic solution to pH 7. One reason us old timers used it for acid indigestion.

Lol, yep my grandfather and Dad taught me that too, both suffered from bad indigestion. But I only had QUICK-EZE on hand, guess that probably would of worked too.. I've got everything on hand now, also managed to pickup a 5 litre (1.32 US Gallon) of Isopropyl Alcohol, same place has Windex in bulk...lol.. I manage to take the Mother's protective coat off the blade, took a few goes with Windex and Isopropyl Alcohol but the oil is sticking to the blade now.

Yep mothers can remove the microedge from a blade if used heavily. I did it to a sword by accident. Ricky from the brand of which we do not speak here told me it happens if your not careful..which I wasn't on my first etch attempt lol.

Micro edge, I thought that Katana's don't have the secondary cutting edge like European swords? Either way I avoided going anywhere near the actual cutting edge (not cutting my finger again.), Plus I polished from the back of the Katana so none of the cloth/Mother rubbed along the cutting edge. I did wonder if you could carefully sharpen a blade by using Mothers along the cutting edge and pinching your fingers together either side as you run it down the blade...lol...

Congratulations on a gorgeous sword (and I'm not even a katana guy) and on a wonderful job etching it. The way you took advice and acted on it was very cool to see, you're going to be an excellent asset to the forum, won't be long before your're one of the ones giving advice.

Any abrasive, even really fine, will abrade metal, that's what it's meant to do. If you rub any abrasive over the finest part of the edge, you might reduce the sharpness a bit of you overdo it. Fine abrasives are used for super sharp polishing of cutting edges on chisels and wood turning tools, but you don't rub along the edge, you use a bench grinder with a polishing wheel made of leather, felt or other material depending on the grade of the abrasive. Not relevant for sword sharpening really.
The 'micro-edge' reference in the previous post refers to the outermost part of the blade's edge, which is very thin in every blade, and not to a secondary bevel.
Hope that helps!

Cleared that up, thanks. Things that you don't think about or don't realize, but the more we learn the more we can help others. Well the Katana still passes the paper test, so I guess no dullness, I'm sure as heck not running my finger over it again..lol... One day I will need to sharpen it, so that will be my next test, but I'm thinking about getting a cheap Huawei beater to practice on.

Microedge is the very smallest point of the edge. The cutting point. Mothers can remove just the slightest bit of steel and dull the very sharpest point. I did it. Microedge has nothing to do with secondary bevel... No mothers will not help you sharpen. Tried that too. It seems to melt the edge. Just be careful and you won't have this issue. I was pretty wreckless in my first tries and over applied it lol.

Honestly so did I for first 2 applications, but following Josh's instructions in taking it easy I didn't rub hard at all, even when removing the Mothers, none spilled over to the cutting edge. After the first 2 goes I realized it not doing anything so I applied sparingly with only the slightest pressure rubbing on and a little bit more in wiping off. To wipe off the Mother's I followed the same procedure as you do for wiping off the old oil when cleaning, running the rag down the blade to the tip. I think it worked out to be 6 full light applications each side with a couple of little area's getting a little more attention to make it look even.

If the blade catches on the back of your fingernail rather than sliding off, your blade is sharp, resist the urge to run your finger along it!

Lol I found that out, You can actually touch the cutting edge, and it doesn't feel sharp, run your finger along and you find out how sharp it is. On another thread I was saying I fell into the Katana myth, that they are razor sharp and will cut your finger at the slightest touch, so I gently touched it, didn't feel sharp, moved my finger an inch..ouch..lol..

That's the niku rounding off at the edge. It'll make it feel rounder upon pressing, but the slightest lateral movement and the edge will grip. The 'thumb test' isn't really accurate for katana due to their niku. Paper tests are better, best is tatami

The 'thumb test' isn't really accurate for katana due to their niku. Paper tests are better, best is tatami Yeah I noticed that with the paper test, I thought the sword wasn't sharp when I first tried it. I placed the blade on the edge of the paper and it didn't cut just indented, but when I repeat with the blade moving, smooth clean cuts. Went through a 4 2 litre coke bottles like butter yesterday, using different parts of the blade (sorry for the non-metric users). I guess that proves the blade is still very sharp from Habaki to Kissaki...lol.. Being a first time "real" sword owner you have to learn these things. I actually hope this thread helps first time buyers/owners, cause I know I've done all the dumb things, but managed to fix it. Very daunting at first, holding this weapon (sometimes very expensive one) in your hands for the first time, not knowing if what you do next might wreak it.

I cut myself the same way with my KC katana when I first got it. It has a lot of niku and didn't really shave paper well but cut right in as soon as I slid my finger lightly on the edge. Very deceptive. You've basically christened your blade -Josh
