    I appreciate what you did here. There are some that think they a knife genius. When in fact when you look around the web you find all sorts of opinions and points of view and beliefs. I like to hear and take in as much as I can so I can decide if it's rubbish or not. Who cares about a persons voice as long as it is intelligible and is backed by solid thinking. If you don't like it just move on. I'm amazed how so many people who criticize others have in fact so little to offer in terms of healthy dialog or as in many cases nothing to offer of any benefit at all. If you offer a fair criticism to open a fair-minded intelligent discussion instead of bashing the contributor we all gain nothing, we all lose instead. I found your presentation enlightening of well-thought-out benefit to many of us knifers. Keep up the good work. I respect the time and effort that you put into sharing with us.

    Cool vid Kyley, very interesting to see the blade geometry at this level of detail. If you feel like doing more like this, I think it is very worthwhile. Cheers!

    Great video! I'm really getting into microscopic analysis with my sharpening as well.

    Thanks for the post, Kyley. I am so grateful that you are willing to share your vast knowledge. I have always loved knives, but I can see that I am an infant when it comes to understanding all of the parameters and how they effect blade performance. Keep up the good work. God bless. John

    If you take a very fine graduated ruler and show that magnified and then put the same ruler next to the image on the screen it make make it more obvious for someone who isn't familiar with magnification settings.

    Yes, more microscope! Very interesting stuff. Would like to see a close up of the edge after using finer grit sand paper & stropping. Great video, thank you! :)

    Great explanation. I am resharpening one of my test knives now using some water stones. I have never tried them before. I am reprofiling the edge and then I will be trying out some the test that Cliff gave me. I will take extra care with the micro-bevel.

  • @knivesandstuff
    @knivesandstuff  12 років тому

    the reason for the micro bevel is that its a lot less steel to hone and resharpen before you need to reprofile the entire convex bevel. i could have made it the same geometry without a micro, but then there is just that little extra steel all the way up the bevel to hone.
    the micro is still probably only 10-12 per side.

  • @jstwatchnread8420
    @jstwatchnread8420 Рік тому

    There is paradox, when you strop to razor grade, it make even more sharper, but also remove the sawtooth like edge, that reduce the cut speed ability...

  • @flyingcobber
    @flyingcobber 12 років тому

    Awesome video, and glad you started at a 400 grit. That seems to be a very practical grind and I can see it makes a great performing edge, with the right micro bevel of course.
    A comparison video to higher grit grinds might be interesting.

  • @mrbluenun

    I have subbed BTW. Can you let me have details of the microscope you are using please?
    You have made my mind up and I want to get one!

    thanks for sharing this, very informative ... I am new in the sharpening and believe a microscope could give me a good help ... what you think? Also can you suggest any Microscope on the cheap side that I could buy? thanks

  • @CliffStamp
    @CliffStamp 12 років тому

    They all look the same under a normal light microscope. In order to see the actual characteristics of the steel (aus-grain, carbides, etc.) you need to polish and edge the surface and then look under high magnification, 1000X is normal.
    As Kyley noted, all the light/dark spots, etc. are just the scratch pattern in the steel, they are not the carbides, etc. as some people have mentioned in other videos.

    Lots of beliefs and misinformation in knife sharpening. This video is the best and to-the-point. Kudos

    Great vids and an interesting playlist K.A.S. You just got me to sub!
    Tip: (For what it's worth)
    For a standardized size comparison which anyone can reproduce.: Use a "period" (full stop) from a phone book.
    - Cut out a period creating a rectangle 1mm wide by 10 mm long, giving you space for tape.
    - Tape this sample to one end of the knife to easily refer to it during filming.

    is that a youtube video? I thought id seen them all. will have to go back and look

  • @mrbluenun
    @mrbluenun 12 років тому

    Nice video, have you tried comparison with a new Wet Razor Blade? I know they are very much more thinner than your knife so the angle is something less that perhaps 10 degrees I am guessing. You could sharpen another knife or the front or back end of the one you showed under the microscope and instead of stopping at 250 grit carry on to 1600 and then to strops with 10, 5, 2.5, 1, 0.5, and 0.35 µ. Flicking between the two grinds you will be amazed at how fine a blade can be.

  • @knivesandstuff
    @knivesandstuff  12 років тому

    I've never even tried, and dont have abrasives fine enough to acheive this. the type of edge that can do that wont last in normal knife use more than a cut or 2. but certainly its achievable.

    Awesome video! I wonder what the tip of a ball point pen looks like at that magnification? I bet the ball has all kinds of imperfections and fuzzies stuck on it etc.

    Very good video, question I have heard it is possible to cut a hair by just dropping it on a blade... have you been able to achieve that level of sharpness? I have been able to cut a hair with very little pressure but not by just dropping one. What do you think is this possible?

  • @oldhairpin
    @oldhairpin 12 років тому

    Love it. I want a USB microscope now. Now then, is this why you put a micro bevel on my friction folder? And, should I be looking to put micro bevels on my Falllknivens? Speaking for myself, I want much more stuff like this and trying to understand the physics. Take care, Ben

      Danvil generic ones you find on Amazon or eBay if you search 200x or 400x USB microscope. Normally 40-100$

  • @knivesandstuff
    @knivesandstuff  12 років тому

    done that before for other things. it sucks. zooming issues, cannot do other off screen things. at least this way I can move the camera to show outside of the microscope.
