Thanks for the advice.

Cut the meat well and just had to wash it with soap and water. I am going to hang it from my BBQ tool rack good place for it I think.
-
I treated it and it works great so far but I am going to try steak tonight so we will see how well it holds its edge.

This is my first completed knife. I have made blanks but never made the handle until now.
I used a broken Bellotta Farriers rasp, normalized 3 times, and drew down the existing tang. Then I forged the blade from 6" (original broken rasp portion) to 9" and worked on uniform thickness and a straight blade. I then split a piece of oak and burned in the tang on both scales. I drilled the tang and then hardened the blade to a straw/bronze over my stoves burner. I then made 2 pins out of brass brazing rod 1/2" x 1/8". I made the pins pointed on both sides, placed them in the holes in the tang and used my vice to force the pins into the oak scales. Then I drew an out line of my handle profile on the wood and used my belt sander to get the basic handle. Then I switched to 400 grit and finished up the blade and handle. I then used epoxy on the tang and pins to permanently fix the handle in place. Then I used boiled linseed oil on the handle. I buffed the knife and used bees wax on a small buffing wheel to further finish the handle.

Yeah I may keep it for that. I was told a new formula to help green sand like mine. Use 1 cup of wax (paraffin, bees, candles already made, whatever). Melt it and then mix in a 1/4 cup of motor oil. Mix into sand and it will help bind the sand together like the clay. I was told to add it to my green sand mix as another additive allong with the clay. It will smoke a little more but it will help keep your molds clean, help hold finer datails such as fingerprints, and keep the mold from falling apart when separating the flasks. I will try this soon and post my results.

I had this from my smithing instructor at Pacific Coast Horseshoeing School, Chuck Pressnail. This was the first time most of us had put hot steel to hammer and anvil. "OK, you have 1 hour to make a perfect horseshoe." 1 hour later I had a roughly rounded 90 deg hunk of metal. Chuck then says, "I lied it will take you your whole life to make a perfect shoe and then you wont notice when you did. Save that shoe so you can see how far you have come."
I still have that "shoe"
Another one from Chuck that I still use is " you can only bend metal up." Meaning that if you want to tweak your heals on a shoe (or any other piece of work) hit the low side to bring it even. (My modification was "Yeah unless you get it hot and use the edge of your anvil.")

We have a great time and that little anvil may come in handy sometime. Next week we will not be able to have our forge day, but we contacted McLellan Blacksmithing and we may be able to go on a field trip there the next week.

Week 5 in the bag. We started a few projects this week. I made a hoof pick (I try to make one whenever I start my forge to loosen up my shoulders), a bottle opener (correctly tested) with a glass marble inset into it (took it home and buffed it to a near mirror finish), normalized a putter head to make a spear, and started modifications on a useless pair of hoof nippers into a set of useful tongs. I punched the rivet out to make them easier to work on later(no Pic). Norcal worked on a forge hook, getting the bosses on his tongs just right, made a drift for tomahawk eyes, welded up more of his swage block, and drifted his tomahawk eyes. (all of that is cooling in a designated HOT area in the 4th pic) A very productive day even if we didn't finish much.
Norcal got his forge so hot that it was molten between 2 firebricks.

I use a 4" od pipe with 1/4" walls and a 3/8" plate oxy/acet welded to the bottom as my crucible. They will slag out after a while but mine has lasted for 200 melts and looks like it can go for at least 50 more. But I am using this forge to do it and I place the aluminum directly under the flame, not the crucible.
-
If you melt it down, all they will pay you is dirty scrap prices. I have a bucket full of ingots for my casting and I will never get what they are worth unless I make something like this out of them out of them.
Oh and did you notice why the counter kept burning? HINT...... they left the hot crucible on it.

Here is a few more pics from our forge day yesterday.
My little forge gets so hot with that door open, you can burn your hands in a second. We used a pyrometer and gauged it at 2100*F!! That was only at 5 psi too. I wonder how far I can push it.
Norcal's forge was at 6psi and he got it up to about 2350*F.

Here it is week 3 of the continuing forge days with Norcal and I. We decided to make another hardie tool, this time a bottom fuller for me. We didn't get far as I had Farrier clients next door to take care of first. (Thanks to Norcal for the referral)
One thing I never expected when making our own hardie tools is how fast a small anvil like mine can heat up, and how long it takes to cool down after.
-
Norcal and I had another forging day today. We got to use my new turning fork to made him a new hold down for his pritchel hole and i finalized the size and form of my Farrier's rasp knife. Time to heat treat and put a handle on it. I am very excited.

I have been busy lately with forging everyday I don't have Farrier clients and wanted some input.
I made a jingle bell and heated it to a bronze color
finished my turning fork hardi tool that I started with Norcal
(yes it is a little uneven but i think it will work)
And started a Rasp knife
hope you enjoy.

Thanks guys we had a great time and yes Tongs are the next project. We live close enough to each other that we may make this a weekly event so expect more pics from both of us.

Norcal and I had a great forge day and wanted to share the fun.
Fueled by Smith and Forge Hard cider.
We worked on a few things including the start of a fully forged turning hardi tool for me and a few tomahawks and a file knife started for Norcal.
Norcal also helped me weld on some separators for my hammers on my anvil stand.
We also figured out that we have too few tongs between us we only had 6. I had 4 of them :D . Just more things to make in the future.

I found a new mix that works well and is not expensive. I used 20 lbs of white ash urn sand with 2 lbs of bentonite clay. This mix holds together much better than my first mix and captures finer details.
