Hi folks,
I have used an "iron pin" (traditional tool) before but on my folded Huawei, I can't get the same flawless mirror finish on the blade flat areas that Huawei did. I wonder how they did that? Belt polisher? I use my iron pin and I can put some shine back from where I used ha/jizuya, but i am still leaving tiny scratches. I have a Dremel tool. Should I get use that with polishing tips? Or what? China is too far away to send off (est $100 round trip).

Probably belt or large buffer wheel polish. Highly doubt they'd be doing it manually. Nothing against Huawei, I like their stuff.

I’d be literally shocked if any production sword used burnishing needles as were traditionally done to shine the shinogi-ji and mune of a katana.
In my production sword polishing I just polish up to a very high grit level (6000+) and buff with a polishing compound. That gives you basically mirror without the burnishing.

Micromesh cloth and lapping film here. Used those for a mirror polish on knives.

Just to ask, has the finish on your needle gone off, or you omitted using the wax, or anything like that? Part of it could be the difference in steel.
I've used buffer wheels chucked in a variable-speed drill and applied linearly down the shinogi-ji (to avoid hollowing and shinogi erosion) with polishing compound on them, and had luck with it on my Chinatanas.

"In my production sword polishing I just polish up to a very high grit level (6000+) and buff with a polishing compound.

My burnishing needle is very hard steel, and I had decent success with older nihonto, but not so good on modern production blades.

I’d give it a go with a metal polish as I’ve had good luck with Metal Glo. The thought of stropping it would be in the back of my mind.

High polish and buff should give you a convincing effect. Especially if you mix with a good hybrid polish and add some magnetite staining which is what I do... that blues up the ji relatively nicely.

.............I had decent success with older nihonto, but not so good on modern production blades. RinC OK, IMHO, it's the steel then. If you consider what burnishing actually does physically, that's no great surprise. Polishing is looking like your best bet.
