    Electron Microscopy of a knife blade

    I was in work using the SEM (scanning electron microscope) when I decided it might be interesting to put my knife under the microscope. Thought some others maybe interested so here are the photos. Unfortunately I left some confidential info on the bottom and had to delete the scale bar. The knife was a griptillian.





    It can be seen in the last image that there is a defect in the steel. I don't think it would cause any issue on that scale but I was a little surprised.
    Here are some of an okapi slipjoint.



    I thought this was interesting As you can see a bur in the top half of the photo which has broken away in the bottom half. There were less faults I think because its a much simpler manufacturing process.



    The last one is an up close of the okapi symbol
    I will add the other knife when I get time

    I would really like to see them - that steel has a lot more flaws than I imagined and I'd be interested to see if the cheap as chips Okapi looks any different. What kind of sharpening has it had ?

    That's interesting; can you see that chip on the edge with the naked eye? Or feel it?

    No you cannot see any of the damage with the naked eye. The red writing is the magnification so they chip is shown at 6 thousand times (roughly I deleted the scale bar before writing on the mag and had to guess based on what i remembered but they wont be far out.) sharpened to shaving sharp on a sharpmaker.

    I like to see it done again after Longstrider had worked his magic on it!
