- Ok, 10X might be a slight exaggeration but man oh man, my results have skyrocketed since grabbing a few kangaroo tails and turning them into strops! As suggested by Dr Vadim (RIP) from Knife Grinders Australia channel. The difference is chalk and cheese. I’m now achieving double digit BESS scores every time.

The amount of information you share is soooo appreciated 👏 👍.
Thanks for the Bison leather idea. We have a Bison meat connection. I'll see if i can get some leather from them.
Thanks again for the constant education 🙏
I've sent an email to the government requesting information. But as mentioned in the video, it's illegal to sell animal products from a protected species. The few exceptions are three states in Australia who can sell to each other. However Dr Vadim was selling and shipping these internationally. I'm not sure how so maybe there is a way. As soon as I get more information I'll share it.
Glad to hear this stuff is interesting to you. It's fascinating to me, Chilli seems uninterested.
Great info i will await answer
I'm pretty sure that he meant Water Buffalo leather, which the Aussies have lots of, rather than Bison leather, which they don't.
@@CrimeVid Actually, I'm not sure what I meant. I only remember buffalo leather, it was in the early 80s and I went to a lot of parties. It was horribly uncomfortable, stiff and bumpy.
really cool....i would love to see some testing to see the minimum ammount of stropping passes for an effective result. are both strops necessary?
@@chuckpen29 no, I don’t think so. But I had the left over piece and wanted to test it in both a hard and soft surface. Yesterday I made a hanging strop so now I have three…lol I just like to play making things.
Passes needed are 10. It’s already been tested by Dr Vadim. He found a great improvement at 10 but no further improvement at 20. I like to do 10 medium hard pressure on the hard then 10 light passes on the spongy at an increased angle to make that root is gone. It seems to work.
@@iSharpen yeah....i read the same study he did. i ordered a hanging strop and cannot wait to test it. not many options for kangaroo leather outside of australia unfortunately.
@@chuckpen29 go to your local leather supplier and rummage through some other animals. I’ve seen buffalo leather and that seems quite bumpy and tough. Might do a similar job.
Why are the bevels from the factory so short compared to how you sharpen at 13°? I understand the lower angle you go the larger the bevel but what angle does it come from factory?
@@vinnym5095 I’ve never had the chance to measure a factory bevel but I’ve sharpened knives that have never been sharpened but are used and blunt. It seems to be quite a short angle. They seem to be about 40 total. They’ve very sharp so the edge is great but the bevels do seem to be very small.
My Tormek is probably almost 30 years old. I had one of those grey wheels. I did try grading it for coarser and finer, but it was always very inconsistent. The wheel never graded true all the way around.... I do have the diamond wheels, but have never mounted them. They didn't make a coarse one, finest is 600 grit.
I am curious about your angle, I think you are saying 13 degrees. That seems rather fine to me, like straight razor type edge. I would consider the 20 or so degree bevel to be better suited for most kitchen use.
Tormek T8s are tough as tanks. Great to hear that you've had yours so long. I hope to pass mine down to my dog when I die.
I've never had a problem grading the wheels evenly with diamond plates but I can see how you might have a problem with an old glazed grading stone. Perhaps try my diamond plates method or a new grading stone.
13degrees per side (dps) is a bit acute for low or medium quality knives - agreed but for high quality steel it's totally fine although I mostly tend to stick to 28-30 for 80% of the kitchen knives that come across my bench.
20 degrees per side is a tad too obtuse for a kitchen knife in my view and more suited to hunting knives, cleavers...etc which will take more abuse. But if you're finding 20dps works for you that's all that's needed. We're all different.
Appreciate your comment though. I look forward to more.
I don't even know where my grading stone that came with my Tormek is. Seems like it was 2 sided, one coarser and the other finer. There are diamond wheels that go on the Tormeks now. Most of my bench tools are sharpened on diamond plates. My personal kitchen knife is old carbon steel, My girlfriend's knife is a Wustoff. She can taste the difference between things sliced with our knives.... A more obtuse angle would probably not work on my carbon steel knife. Tormek did have a black wheel they came out with that lasted a lot longer than the grey ones. I just haven't switched over to my diamond wheels now. Thanks!
@@robohippy tell your girlfriend she’s right. Different knives slice differently through cells and the Japanese have a lot to say on different steels, different flavours.
As for the wheels, the SG wheel is highly adaptable and very gradeable which is why I like it. I haven’t had much to do with other types of wheels so can’t comment either way. Because I’m a commercial operation I have to depend on reliability so I’m a “stick with what works” kind of guy.
Yup! Ask 10 people the same question and you will get at least a dozen different answers..... I have to experiment..... Curiosity!
Thanks so much for your videos. I recently bought a T4 so very helpful. I’m still a bit confused as to how you’re feeling for a burr when you do alternate sides like that - won’t you be forming and then removing a tiny burr each time you reverse?
Hi, and thanks for watching. Yes I suppose you are removing it but then reforming it again when you switch sides. The point of it is that you can only form burr when both sides meet at the top and you have an apex with no rounded top left. A pure triangle top. That's when you know you can stop grinding.
Is it difficult on a Tormek to get consistent bevel width?
@@goingforspeed it’s very easy. That’s one of the best parts. It’s a guided system. So the bevels are always even. The operator can go faster or slower or be uneven with his pressure that can affect it but once competent, the bevels are perfect. Looks just like (or better than) factory.
Watch some of my other videos. I bring the bevels up close to the camera and you’ll see.
I received my Buffalo hide today. I have 4 x 12” by 12”
@@robertdewalt8711 is it bumpy?
@@iSharpen . One side is smooth, one side is rough.
@@robertdewalt8711 excellent. I look forward to your findings.
Where can I get Kangaroo tail leather? an you help me with this issue?
G'day Randy, what country are you in brother?
I've ordered a piece, but it won't get to me until the end of the month (slow boat from Australia). Still, I'm skeptical that this is actually the key, as opposed to simply going with the lower edge angle. Most of the really low BESS scores Vadim got were achieved with edges at 12° per side. Also ... not to be a wet blanket ... but when you use the BESS clips, as opposed to the pedestal, you have to add 10% to your BESS score to get the "official" result. That's according to Edge on Up, the maker of the BESS system.
Using cartridges is the best way to get a consistent result. There's no way to be consistent with the string cartridge method. Pull tighter the score gets lower. Slacken the string and the score gets higher. I've tested it. In fact it was the first thing I did when I got my BESS scale. I was shocked at the variation I got with the string pull method I see that as flawed. Cartridges are always the same consistent tension on any given day.
The kangaroo tail benefits have been proven in my own videos. Angle has something to do with it, sure but only when comparing massive angles with tiny angles and if you leave the root of the burr on, no lower angle will help you. Getting a clean apex is the most important thing and a lower angle is no substitute for that. I get double digit scores at 30 degrees as well. I think too many people are overly obsessed with knife bevel edge angle anyway. Sharpness is all about a clean apex.
Good luck with the kangaroo tail strop. Abandon your scepticism. It works. I've proven it.
@@iSharpen You can get a consistent result with the fixture if you tension the string with a 100g weight. There are a couple easy ways to do that. I use a hemostat with a little bag tied onto it containing a couple weights (totaling 100g). You can also use an actual 100g weight and a magnet or an alligator clip. The benefit is that it's a lot cheaper than the clips, and you don't have to do math to get the real result. 😀
I'm really looking forward to trying out the kangaroo tail. I've been wanting to try it since I saw Vadim's video years ago.
@@BladeLabMiami I’ve just run out of clips and at 60c each they’re a bit expensive. I do have a full real of wire in the cartridge that came with the knife. I’m going to have to use it eventually.
But even at 10% lower than reality it’s still good to get below 100. I expect ambient temperature might also play a part. Then again ambient humidity plays a part in cigarette paper tests as well. It’s not an exact science but getting a double digit score means the root is gone which is the main thing for me.
I don’t think I can compare my score to your score nor should it be considered relevant. Scientifically speaking, the main thing is a score on my machine on the same day compared to a previous score. In other words, has there been an improvement?
Still, it is good to see those numbers come up under 80. My best is 56 from a VG-10 IKEA knife of all things. But that was before the kangaroo tail strop. Kangaroo tail strop is a new thing in my life. Took me a while to find some. Glad I did as it makes all knives sharper which tells me that all this time I was leaving a wire edge on knives. Sure am glad to have crossed this bridge though.
I look forward to seeing your testing videos after your tail arrives.
@@BladeLabMiami I just recorded a video of a side by side test between the clips and the cartridge (weighed down by a welding spring clamp). But sadly I mucked up the recording by forgetting to press record on the second test after sharpening and also leaving my mic off so no audio was recorded in one of the clips. Dufus confirmed.
Sadly I used my last three clips so I can’t reproduce it without buying more clips which I might do for future testing. The surprising thing is the results were mixed and inconclusive.
In the before sharpening test the clip recorded a 117 and the cartridge recorded a 130 so the cartridge was 11% higher which is consistent with the 10% rule.
However, after sharpening and stropping the clip recorded a 90 score and the cartridge recorded an 80 score which proved the exact opposite of the 10% rule.
I think what this proves the most is that the cartridge can’t be trusted as I’ve proven (to myself) before. I actually did the test the very first day I got the BESS tester because I was curious to see if tension variation matched with result variation. Even though I used a weight to tension the cord the equal amount each time it read over on one test and under on another test.
I’ll probably stick to clips for consistency I think. But I might do some more reliability testing with the cartridge to see if I can get some more insight into why it’s so unreliable.
Side note:
I noticed that Dr. Vadim just pulled the cord with his fingers while others are using the clip and weight method.
@@iSharpen I've recorded more than a few videos like that myself. lol
As far as variation goes, we also have to account for the fact that the test is only testing a fraction of a millimeter of the edge, so even if the tester itself is completely consistent, results may have some variation due to inconsistencies on the edge. Having said that, I usually get repeat results within 5-10g with a fresh edge.
I don't think using a weight is strictly necessary for my own use, but I think it's good to use it when recording, just to eliminate that potential variability. In practice, I've done enough tests to know that just pulling the filament tight enough to remove any slack is equivalent to using the 100g weight. I'm sure Vadim figured that out as well. He sometimes did the test a little faster than I'd like to see, though. Speed is more of a wild card than tension.
Great video ,I live in sweden and I cant find Any kangaroos here 😢 I have been all over the internet and only kangaroo leather avalible , dingo if you have a dealer thats willing to ship it to sweden ? Anyway great job m8 keep em videos comming 😊
Try buffalo leather. It's just a guess but from what I remember it has bumps, is super tough and is rough too. Might work. I'm making enquiries into seeing if I can sell it internationally. I'll let you all know if I can.
Thanks for the encouragement. Much appreciated.
Where's can I get one.
I see there are a few on Etsy for sale. Not sure how, unless I'm misinterpreting the law. Could be. I'll find out this week.
