Cool, good to see you back up and going. Looking forward to some pics.

Here it is.

The stainless PM that we use has had great reviews. I personally used a gyuto made with this material in my own kitchen for about six months and love this steel. Thin grind, distal taper, rounded spine and choil. I seriously thought about keeping this one for my own kitchen, Jackie won't let me keep any more knives.

Love and respect

The blade for #2 is profiled and heat treated. The ferrule is formed and the handle material is picked out. I think that I'll take some pics of the remaining process to show everyone how we do some things.

At this point we are about 1/3 the way done.

The damascus and mokume pattern will come out after polishing and etching.

I love that curly Koa.

That is cool, you are pre-shaping the mokume. I just assumed it was ground to shape with the wood. I love WIPS!

We like to do a rough grind and the distal taper on the surface grinder. It makes for fast removal of metal. The final grind is done on a 2 x 72 belt grinder.

I loved the second knife - stainless Herring bone damascus with a core of S90-V (stainless super wear resistant) 270mm and I want to buy it!

Reserve it for me, please!

Keep up the great pictures Hoss, we always say pictures don't do your patterns justice, but we sure do still love seeing them though. I think I like the WIP shots more than finished product shots, I mean we've all got finished knives, it's the process we don't get to see all the time.

This is great! Interesting to see you use a work rest, and some others do not. I'm sure it allows for even greater consistency, and now I think I'll Jimmy one up for my grinder.

DevinT

For me the work rest just gets rid of one more thing to think about.

DevinT
11-09-2012, 08:31 PM
Big trouble etching!

Every once in a while I get my self in trouble etching stainless. It never happens with carbon damascus. Something happens in the heat treating that causes patches of uneven etching. The more I mess with it the worse it gets. The problem is worse when there are several different steels in the mix, like damascus with a core. And it always happens when people are watching.

Look closely near the tip and around the name stamp. I will remake the blade, no problem. It just hurts to have to relearn what I'm doing some times.

I'll regrind this into a line knife.

Can't you just put it down to random variation and keep it the way it is? Like when Dave etches the Hiros and sometimes they look crazy

JasonD

I also take such "scrap", in case you were wondering. No handle required! I'll pay shipping! :D

Seems such a shame to see a beauty like that get thrown in the junk heap

What if the blade was finished and no etching?
I am probably wrong but wouldn't the pattern show subtly.

DevinT
11-10-2012, 11:40 PM
I may do that. Most likely I'll regrind this into a smaller blade and etch, should be fine.

Whats the purpose of the heat treat foil?

kalaeb
11-11-2012, 09:47 PM
Whats the purpose of the heat treat foil?

My understanding is to prevent carbon migration? I could be mistaken though.

Lefty
11-11-2012, 10:17 PM
I think it's to help keep oxygen away from areas you don't want it (inside). That way you don't get internal pitting/weakness. But, I could also be wrong. I have asked so many questions that I'm now getting the answers all confused. Haha. Although, Matt, you might be right...maybe it ensures more even heating, which allows everything to "mix" properly.

SpikeC
11-11-2012, 11:32 PM
It keeps the carbon from burning off. Oxygen steels carbon.

DevinT
11-12-2012, 12:03 AM
The foil keeps the steel from oxidizing at high temperature. The oxygen can combine with the carbon at the surface of the steel to form CO and CO2 and cause some decarburization. Oxides also form which are ugly and very hard.

It protects the steel while at the hardening temperature.
