First Knife, no power tools to be used.

[Cake_14N]

I asked Mr. Harsey if I could begin a post here to solicit feedback during the creation of my first knife. With his permission, I will begin.

Some of the basics:

1. Knife will be made from a piece of 1/8 x 1 x 9 inch CPM 154 stainless steel. Lesson learned allready, this steel eats hacksaw blades. Two blades dulled just making a cut across the piece of steel.

2. This knife will be made using hand tools only, no bench grinder or other powered grinding tools. I know this sounds foolish, but I was taught that before you can appreciate using modern technology you need to learn the basic mechanics behind the tool. I know I will regret this decision as I have started using a file to remove excess metal from the bar to shape my blade and it is going to take a very long time.

3. Blade shape is a simple, slightly pointed blade, 3 13/16 long with a 5 3/16 full tang. I started with a 9 inch long, 1 inch wide, 1/8 inch thick piece of steel. I actually measured the blade in one of the pictures in a magazine and worked out the ratio of blade length to handle and used that conversion factor to scale my knife to the piece of steel I had to use. I guess us Intelligence types make things difficult using math in public.

Stuff I still need to figure out/acquire:

1. I need to come up with a way to heat treat. I have a book by Mr. Wayne Goddard that shows how to make a gas forge using firebricks. I just need to get across ABQ and stop into the ceramics store and buy what I need to make the forge. Then I need to figure out temps and times.

2. I purchased a few pieces of wood to make the handle, but I think I ordered the wrong thickness. The wood pieces I bought are very thick, off the top of my nugget, I believe they are 5/8 inch thick and polished on both sides. This will take some filing to get them to the size I need for a comfortable grip.

3. I need to acquire the sandpapers necessary to finish the blade. I do have a dremmel, so I will most likely use that for the final polishing, but I still need to hand sand before that.


Enough for now. Thanks for the opportunity to share this project.

I will update this posting soon and add pictures.

When you start numbering them, I'll buy No. 1 for a hundo.

Looking forward to the progress... But geez that's A LOT of work. Have fun I guess

Dusty,

Sir,
With the QP next to your name, it would be an honor to have you in possession of a tool I made. I will definately let you know when I feel I have made something worthy.

BRAVO-SMASH,

Yes, it will be a lot of work, but nothing worthwhile is ever gained without the blood, sweat, and tears of the person behind the creation. It should be a fun ride.

Cake,
Thanks for posting this thread as we discussed.

Can you post pics of steps? That would help.

If I can advise on one thing and this is for others to read too, you are probably not going to heat treat CPM 154 to it's full potential with any type of home built furnace/forge/oven on the first try.
The times and temps are too critical and nobody knows what any oven does without first dialing it in (calibration).
You don't know your hot and cool spots or if your thermocouple is right.
Also with any gas oven it may be tough to control and hold temps over the periods of time that is needed with your steel.

A small 1% error in temp reading can cause problems, a 5% error can cause big problems in heat treating air hardening steels like CPM 154.
You will have a lot of hard work at stake by the time you heat treat.

If one used a common high quality oil hardening steel for your set up, this might go better because there are good ways of judging temps without a thermocouple with a steel that gives us a little more latitude in heat treat.

CPM 154 is an exceptional steel, here is the chart: http://www.crucible.com/PDFs/%5CData...20CMv12010.pdf

Bill,

After reading your Link, I'd wager that the "Salt Water Quench" serves a Dual Purpose!! It not only quenches, but serves as a Passivation Process to enhance the "Stainless Qualities"!!

Just peeking in,

Take Care!!
