    I got the same set of hardness test files to test my 1075 knives. Even after followed the instructions that came with the files, I wasn't 100% sure if done correctly. This excellent video with clear instructions reaffirmed my test results. Thanks!

      Thanks Red glad it helped. They are a super handy tool. Beter than using any old file thats for sure

    The sound does change, but the large bar is a bad example. A larger piece will have a lower resonant tones, so it will sound deeper. Test similar size pieces, for better results.

    Awesome video. Thanks I am going to put another order in with gameco in the next few months. I will have to decide if I want these or not by then. When you HT your 1075 how long do you temper for and how many times? On the website it only tells you temps but not times or number of cycles.

      All steel should be tempered twice for 2 hours each time, coming back to room temperature in between the tempering rounds. Use the tempering charts for the relevant steel to work out what temperature you should be aiming for.

    Five years old, but I have a question please (if you're still active). Do you just test this on the very edge? Is that because that area will be removed during sharpening anyway?

    • @batcountryforge5945

      No you can test all over as long as you have ground the scale back and are checking steel itself rather than oxide. Its often interesting to see how the thickness will impact hardness. A slightly softer spine might be preferrable but you need to know that the "working" part of the blade has hardened as you intended.

      ​@@batcountryforge5945Hello again! A quick question please. Should you run the file across the edge or the flats of the bevel? I have a piece of steel that skates on the edge up to about 60, but scratches the flats.
      Also, how much pressure should I apply? I know that's hard to describe...

    Rebranded Tsubosan (chinese) test files. Probably better price for the Tsubosan.

    Rockwell c indicates the shape of diamond used. C being a rounded one.

      Copy, I have a big electronic one now, Ill have a look but I'm pretty sure it does have a round indenter.

      I had a quick google, rockwell b apparently means ball, and rockwell C means it has a cone indenter. Load force is also different between the 2 tests. Good comment, I never would have come back to think about that.

    so at what point do you test the hardness, before or after tempering? i would assume after its been tempered in the oven

      After

      You test wherever you have a goal hardness to reach, wether that is before or after.
