Good demonstration. Could be really useful for a practical katana that you don't want to replace.

Robert McCarter yup it's a cost efficient way that's very effective.

Thank you. I'm following what you're saying and I'm getting somewhere now

I just sharpened my katana with 600 grit wet sandpaper along the edge with the sandpaper folded on both sides. It worked great, but did I mess up the geometry?

[@mdesgro3692]

Forgot to mention, I'm using a stone not sandpaper. I'm sure the results are similar.

[@TheKoolaidman007]

Yes very close

9:36 wet with normal water?
but the sandpaper is visibly dry

[@TheKoolaidman007]

The friction dries up water

[@TheKoolaidman007]

Normal water the soap will help persevere the the sandpaper

[@jackal1743]

If you have a natural hamon line does this affect it? Not exactly sure how this affects it

[@TheKoolaidman007]

The auto body sandpaper gives the appearance of whetstone use which also brings out hamon hada granted it's not better the quality stone
