    Anyone that's ever worked in residential HVAC can tell you sheet metal is razor sharp by default

    Great video! I am a sheet metal worker and the only way I can explain the problem that your having is that sheet metal (at least some gauges) are made to not be too hard as in most cases the metal needs to be somewhat malleable for the metal to be folded and formed to make fittings or ductwork! As you shave the sheet metal down it starts to lose the little hardness that it may have. If you were to use the blade you made on wood you could find that the metal may warp or the edge will mushroom

    For a minute there I forget I was watching someone sharpening a sheet of metal, instead it was like I was watching a older person giving me life advise and telling me to return to the god and stuff. XD

    I love how he talks about life while he sharpens the metal, it just makes me feel that he's genuinely happy with his life and what he is doing

    Your absolutely right about the steel. What you have there looks like cold roll steel which is rolled out to the specific dimensions and left to cool which makes it relatively soft. Where hot roll is immediately quenched after rolled out to specific dimensions. Id be interested to see what a piece of hot roll would do but the issue isn't if you can get it to shaving sharp its how long it will last that way. if you were super careful as you said with that piece after honing you might be able to get one pass on your arm but because of how soft it is it wouldn't make a second pass. nice video though love that sharpener.

    Its all about the angle of your edge. The sheet metal was at a steeper 20º while your pocket knife was at a waaaaay shallower angle making the edge have a lot more hardness for how small it is.

    Great video Cody 👍 I think you helped prove a point that a poorly heat treated blade can be extremely hard to sharpen. If the blade isn’t hardened properly, or is too hard, good luck! Now imagine someone trying this freehand! If the steel is too soft, the edge will roll on the stone. Sheet metal is just mild steel with very little carbon and can’t be hardened. Hence the edge rolling 😀 It could also be the burr you are seeing but I think you probably already know about that.

    Cool video, thanks for making it. As for sharpening 20deg was far to high for that test. It should have been between 10-15 deg for a shaving edge. For example a nice Fillet knife is 5-10deg, thou each person sharpens differently. Also metal composition also has a large factor in its ability to sharpen well.

    I like the wide ranges you cover and answer your comments, I especially like your restoration of old axes. I am kind of an axe lover, I don't have but a couple, but I have one I am working on at this time, would like to send a pic of finished product. As far as different metals taking an edge, yes, most any metal will take an edge, just how long it holds that edge. Thank you sir and keep up the fantastic reviews .

    If your curious as to why its not as sharp, the idea is that most knives and tools are heat treated. This is where you heat the steel up and then rapidly cool or "quench" it, which allows the carbon in the steel to stay distributed evenly throughout the blade. You can then heat the metal back up to a lower temperature which slightly softens the steel, making it less brittle and prone to breaking, which is called "tempering" the blade. The reason this matters is that the steel is probably bending at the very tip of the edge because there is so little material. If you want to try this again but not go the heat treat route, just reduce the pressure you're applying to the blade to sharpen it, this should prevent the bending a little bit better, or as you suggested using tool steel is a great idea.

    It's all about carbon content and heat treating the knife has a higher content which leads to a better hardness and a better blade. With the sheet metal it's not a high carbon steel so it doesn't matter if you heat treated it. It would not hold a edge or sharpen worth a flip. Nice video also. Always like the things you have to say.
