Nothing too fancy here like you other guys are doing, but I'm doing something that I know well and hopefully can share some info on how I etch and polish hamons! I'm making an American style chef knife from 3/32 W2

Here is the profile I printed out from my saved templates

I traced the template onto the steel

I rough ground the profile and drilled the pin holes

Next I made a pattern for the hamon with satanite

That's all I got done for today. I plan on heat treating tomorrow night after the satanite has time to dry!

Looking good! I'm going to be following along especially for your hamon. I'm doing my first hamon on my KITH, so very interested.

Thank you, I see you are using furnace cement which is what I used for a few years. I've just recent switched to satanite and I'm still getting my process down. What are you using to quench your 1075?
 
Ok, got a little more done on the chef knife last night and today during my lunch break.

Got my oven up to temp:

Fresh out of the Parks 50 quench:

Cleaned up and out of the temper oven after 3 1 hour cycles at 400 degrees:

After that I scribed my centerline along the edge:

Ground 45s just to the edge of the centerline on each side:

Then I start grinding my bevels, first I start with 60 grit:

Then on to 120 grit, progressing further up the blade:

Then on to 220 grit and progressing even further up:

And to add, since I grind my bevels after heat treat, I make one pass, then dip into a bucket of water to keep from over heating. I actually skipped taking a few pictures as I'm on to hand sanding now. But I took the blade to 400 with my flat platen, then on to 600 with my rotary platen. Now I start hand sanding at 800 grit, then I will move too 1000, then finally 1500 before etching. Stay tuned!

Here is a video of my hamon etching and polishing process. It's a little long at about 14 minutes, but I think it's pretty good info. Also, I learned something about myself....I have "Sanding/polishing Dimples" lol

That’s pretty cool. I have never seen that method before. I like it.

I missed this earlier. I've been using Canola oil. Will that work OK?

I've never used canola, but I've heard it works ok for shallow hardening steels if you heat it up to around 130 first. Use a candy thermometer and take a piece of steel and heat it up to red in the oven or forge and quench it...that will bring the temp of your oil up. Then quench your 1075

That's what I've been doing for 1084. Thanks again.
