    Since watching one of your previous videos, I've put the same edge on every blade I've got, (when I sharpen them) , namely 600 DMT followed by a 1micron diamond strop.. This helps in discovering how my blades perform, by removing one of the "variables", and the toothy edge works for me perfectly..
    I wish every knife I own was in Magnacut, as that would remove another "variable".. lol..

    Love the cookie analogy! Cookies should have their own HRC hardness scale rating too! In this scenario, a lower number would obviously be preferable, as it would indicate a softer, richer, chewier, more delicious cookie. So a Red Velvet Crumbl Cookie would score like a sumptuous 54 in CHRC (Cookie HRC) whereas that stale Keebler Chocolate Chip that's been sitting in the back of your cupboard would score a brittle 66.5 in CHRC. This metric could also be applied to cheeseburgers, chicken sandwiches and pizza too! While I like your correlation of steel to cookies, I have always personally thought of the microstructure of steel as more similar to Crab Rangoon, with the cream cheese and scallions binding the 'carbides' of the crab together to achieve an ideal result. Aren't you hungry for some Crab Rangoon now, E?!?! I always love it when you put your teacher hat on and do these educational videos, Slater!! I might not understand everything you're talking about, but I always come away having learned something new!!! Great video, Erica!!! 🧡🥰

    “Scratch the surface” on steel. lol. So this helps but my brain always thought heat treat and tempering were the same but i guess not. Would be interested in how the two are different. Now I get microstructure (your video) and cryogenic treatment (another video) dumped on me today. Thanks for taking microstructure…. I’m picking up what your laying down there. Heat treat, temper, and cryogenic treatment differences can still use a little work. While some prefer razor edges I for one prefer toothy. Thanks for picking up some of the puzzle pieces!

      @ericasedc  2 วันที่ผ่านมา

      @@mikehouser7587 I guess I should have specified. Heat treat is a broad term used to describe the process of heating the metal to modify the properties. Tempering is a specific step where you reheat the metal to a lower temperature after hardening. So “heat treat” is an umbrella term just like I used “geometry”, and how a lot of people use “toughness” to encompass a number of characteristics of the steel or geometry being “tough”.

    The geometry of a blade cuts (geometry = shape, thickness, grind, etc.). The finer the particles in the steel structure, the smaller the carbides that form in the steel structure and the more evenly everything is distributed in the steel structure, the better the properties of the steel.

    I’ll have to make a video about this because you’re close but off by a little. You can’t really change the microstructure of PM steels. You can but it’s super time consuming 16-24 hours extra in the heat treat process for a little bit of gain. What you ca do that will make a large impact is run coupons to find the best hold time for a specific steel in a specific thickness at a specific temp.
    Example I can get 1 hrc harder following the 64 hrc protocol with my magnacut HT by modifying the hold time.
