    A common misconception is that more obtuse angles have better edge retention. As long as the steel is hard enough to support a lower angle, the lower angle will cut better for longer than a higher angle. Of course, if the steel isn't hard enough, the edge will roll pretty quickly. And if it's hard, but not tough, it will probably chip. It's always a balance!

    • @iSharpen
      @iSharpen  Місяць тому +1

      Interesting view. I've always sharpened boning knives at 20 dps for this exact reason. My best edge retention (from anecdotal evidence) has come from stropping on the kangaroo tail. I have several professional full time cutters on my client list (meat works, butchers...etc) and they've all reported increased retention since moving to roo tail.
      In your view, what is the best way to test this hypothesis?

      @BladeLabMiami Місяць тому +2

      @@iSharpen I think the roo tail is great -- no complaints there. I'm just talking about the effect of different angles. Vadim, from Knife Grinders AU, had a regular business sharpening knives for a poultry plant. His experiments demonstrated that they were getting the best edge retention sharpening at 12° per side, and that wasn't with exotic steels. They were using pretty standard Victorinox chefs knives.

      @@richardchambers256 cool. The answer is that sharpness is largely a factor of apex edge prep and burr removal as all these angles were as sharp as each other. The lesson here is "it doesn't really matter". Angle (I think) is more of a factor in how easily an edge will bend and lose sharpness due to misalignment. I should do a stress test to test that.

    @lars43771 Місяць тому +9

    Hey Baz, great video! The only way a 40 degree edge will out last a shallower angled edge, is when the shallower edge would get impact or torsion damage(rolling or chipping). If the knife is used for it’s specific task and the steel and heat treat support it, the shallower angled edge will always last longer for pure cutting. Unfortunately a lot of home chefs use their knives in ways that will chip or roll the edge. This is when a bit more meat behind the apex can be beneficial to them.

    Consistently & repeatedly testing sharpness is more difficult than it would appear. I use phonebook paper and attempt to slice a single line of text in half or even quarters. It requires a fairly well refined blade to slice phonebook paper at all as thin paper is more difficult to cut than thicker paper. A sharp blade can cut a single line of text from the page consistently, a sharper blade can cut a single line of text in half and the most refined blades will cut about 1/4 line of text that simply curls into a ribbon as the blade slices through. I’ve found this method of testing provides the most consistent results in a test medium that almost everyone has available.

    What’s the purpose of using the leather wheel hone and then using the kangaroo strop?

    • @iSharpen
      @iSharpen  8 днів тому

      Good question. The leather wheel does a great job of removing the burr that's developed while grinding but it doesn't remove the root of the burr or (as some people call it) the "wire edge" which is a tiny microscopic left over burr which can cause premature bluntness often experienced after sharpening.
      The kangaroo tail has little ridges that no other leather has that (it's been discovered) has the ability of removing the root of the burr (wire edge) and creating not only a more refined (sharper) edge but on that lasts significantly longer too.
      I can prove the sharper aspect with before and after tests as I've done dozens (hundreds) of times now. The longevity is only anecdotal but from my feedback, quite real.

Many people are even happy with the level of refinement you can gain just by using the leather wheel. In fact many of us had no choice until now. In fact until the leather wheel came along, many sharpeners would just deliver the knives with the burr thinking it was sharp enough.

      Ask Oregon if they can get kangaroo TAIL from nature animals. It's very specific and for a good reason.
      It's called a BESS meter. I ran out of clips. Don't worry about the grams. The lower the number the better. I knife should be under 150 because that's how sharp a utility razor blade (box cutter) is. 50 is how sharp a disposable shaving razor is.

    Remember the first comment I posted to your channel when I said something like “from here, it doesn’t look like the point of the knife is touching the wheel”? I listened to your answer and hadn’t thought about it till now. I THOUGHT IT WASNT TOUCHING THE WHEEL CAUSE THE POLISH ON IT REFLECTED THE WATER! Boy am I an idiot 😂

    I have an axe that’s shaving sharp. I don’t think angle has much to do with sharpness, within reason, purpose of use and the strength of the steel is more important, I’m not likely to be slicing tomatoes with my axe, the edges on my kitchen knives wouldn’t last long chopping wood.

    I don't own a single knife that's more than 30 inclusive, and that includes non kitchen knives. Most of my kitchen knives are 15-20 inclusive. Also there is a difference between a keen edge, which is what you mean when you say "sharp." and what sharp actually means, which is cutting ability, which depends more on the geometry of the primary bevel than it does on a keen edge. High quality kitchen knives are in the range on 10 thou behind the edge. That's what really matters much more so than a keen edge on a kitchen knife. If those knives are >20 thou behind the edge, and with such obtuse secondary bevels, they'll cut like pigs. Even if you put a nice 20 inclusive edge on a kitchen knife that's got poor geometry, as soon as that edge is toast, the knife won't cut anything. Good kitchen knives don't need an edge at all to move through ingredients with ease. That's geometry. The only thing the edge itself effects is something called cut initiation, aka what casuals call "bite." And the only thing "edge retention" which casuals are obsessed with effects is how long that cut initiation sticks around. Says nothing about what matters, aka cutting ability, aka the real meaning of the word "sharp" in the context of a knife. And no you don't need fancy steels on kitchen knives. The common 4416 German steel used in a lot of common kitchen knives is plenty good for anyone that isn't a professional chef. What really counts, and what's usually lacking on common kitchen knives is the geometry. This is why Japanese kitchen knives are so popular these days. Even mass market factory made Japanese kitchen knives come with geometry in the range of 10 thou behind the edge.

Anyone that has experienced thinner geometry prefers it instantly. It’s less work with thinner geometry. It’s easier on the hand and joints to use thinner geometry.

    Have to say that it is really depending on the knives. I have an old Hackman knife that was "cheap" but has good, "hard" steel that keep its sharpness well. But then I have Sanelli "professional" CroMo knives that are hard to get sharp and needs resharpening often. They are thin and "soft" and from the beginning the edge was concave instead of convex. I also use the T-8 👍🏼🫡🤗.

    if I can add Baz, when my kangaroo tail starts to crack along the edges, I’ve taken a fine grit wheel on my drum and smooth them out a little bit.
