We used your additions to the HEPK tests and they were greatly appreciated, will add some photos of them when time allows.

This is the test blade pictured above, it made 15 edge flexes with no chips, then 4 180 flexes starting with 62 foot pounds of torque, when it  finally cracked. I have sent the blade to Rex and we should be hearing what he can read with his laboratory equipment.
What we know now is that we can see 5 different phase changes in the blade in the crack, it was very strong, tough did all I expected of her. We could have easily straightened the blade and used it again, can't wait to hear from Rex.

This one with a man from Wyoming, a very good student, learning fast. Good times!

You can have her after the test, maybe you could straighten her out and get some use out of her. Actually I have other blades on the way for you to chose from, handles and all!! But she will be here or with you, looking at her she really has quite a story to tell, I will try to get some better photos and post them up.

To be honest I kind of like her myself!!

A little better photo, the top one is the blade I over heated while hardening, the bottom one is the replacement blade, it is 5 1/4 inches long, came out just right, in good light you can see 5 transition zones, my photography is a little lacking at present, but will be getting better, I promise. The customer for this blade is a little particular so I am also working up another blade, just a little different so he will be able to choose.

Thanks Tom, I just heated it a little too hot the last time and it shows all thee way through, should be fun testing.

These are the men who came to the last testing seminar. I got too excited and did not take pictures or record what happened, this year I plan on concentrating about my job!

Those of you who have something to share, be it some great new process or a failure bring it along and we can all learn from it.

This is the members of the last falls test session. Each one brought a knife to test doing something new and we had a ball. I was too busy running around and learning I did not get a chance to take enough pictures, this year I will take photos and keep a running account of what is tested.

Every year we have a get together of HEPK Smiths who wish to bring something that they have made that will have some special kind of treatment that will reveal something different to those who want to test it. This is my first knife that will be tested, it was over heated before quenching and left a super hardened area that climbs right to the spine. We will test it to destruction this spring. I invite all who are interested to bring something special and share in the learning from what it has to teach us.

Those were beautiful cloths Rad, I am glad you have more. I wiped down a few knives then left for a few minutes and my cloth was gone!! Seems like many folks liked them.

Your daughter is a very nice young lady, you can be proud of her.  I am glad you brought her to the show, she seemed very interested in knives for some reason.

Blade show was absolutely great, got to see old friends and made some new ones. It is still my experience that the more you take the more you sell, I still had a good selection for folks to see on Sunday and sold three in the last hour of the show.

Rad brought some HEPK knife cloths that worked well and really added to the looks of our table, thanks Rad.

Glad you got it working, sure can be a hassle sometimes. That is a nice knife, glad you are using her.

Thanks Tom, somehow I got 3 weeks ahead of myself, panicked and really worked hard, got them finished a week early so had time to ship them this year UPS, so far it is good, now just wait to see if they get there! Some times it pays to not take time to read a calendar.

Attached are some family photos of knives going to Blade This year. These are inventory photos, with price tags included, some of them are spoken for but all are going to Blade. I have taken  individual photos of each of them.

Distortion during hardening cycles is not uncommon. Usually due to the forging methods, or hardening, we found that when we added the post forging cycles all distortion ceased.

For those who are not familiar with post forging cycles it is simple:
After forging the blade to the shape you want, heat it to non magnetic and quench it in room temperature Texaco type A quenching fluid for 35 seconds, heat it back up above critical and quench again then to it a third time.

Heat the blade up to critical for a flash normalizing cycle, From non magnetic to magnetic, immediately re heat and repeat, then heat to non magnetic and let it cool slowly to room temperature, then anneal (I use 988 f,) for two hours a couple of times and you should have no problems.

The post forging quenches seem to be the most reliable method of preventing distortion in blades during heat treat.

I have only used Texaco type A oil, other oils may work just as well.
