Sharpening a Damascus knife with CBN & SJ wheels

Knife Grinders' instructional video
The knife by an Australian knifemaker Jason Weightman is an extraordinary work of Macabre art.
I've named this knife "Styx" - that Greek mythology river between the underworld and the world of the living, the damascus pattern like many streams of our lives running to the tip where the lives end. The porous core of the deer antler matches the skulls decay.

Awesome! 👍

[@shaunm2208]

i see that you do not lift the blade for the tip..thats the mistake i make

[@hansosanchez]

Thank You Vadim! Any "early" experience with the diamond wheels from Tormek?

[@venanzioandreozzi5476]

dove posso acquistare una base universale (US400) a T come quella del tuo interessante video ?

[@gabrielkierulff]

Thank you for the video! amazing tutorial, do you recommend any place in europe to get these CBN wheels?

[@MrNicovdw]

gabriel love to know that 2

[@polarstern5481]

Absolut!

Good video and teaching as always.
Initial Bess Sharpness Score was 385, How much was it after the process?

[@knifegrindersaustralia5158]

Surprisingly, slashing a free-standing cigarette rolling paper requires a less sharp edge than cross push-cutting it - slashing is possible at about 50 BESS, while cross push-cutting requires minimum 30 BESS. First slashing I did with a Global kitchen knife on a corner of the table, but kept hitting the table, so resorted to a protruding sheet of paper as a base in order not to damage the blade.

[@sebastianreddan1647]

And the actual BESS score was?

[@sharpen-up]

Thanks for your expert techniques, reading your "Knife Deburring" book atm, and wow what an eye opener! Question, if you went straight from the standard SG wheel (graded with 80 grit diamond plate to be as rough as it comes), right to the Razer Sharp honing paper wheel with rouge applied, would you have a decent edge, or is it imperative to set the edge around 1000-1200 grit? What if you set bevel on Tormek SG wheel, then did a couple passes on the grit paper wheel, then finished on honing paper wheel? Thoughts on this? Thanks as always, from Sharpen Up Mobile Sharpening!

[@knifegrindersaustralia5158]

Mate, all you need as a mobile sharpener is a coarse stone or CBN wheel and the Tormek composite wheel, and you'll be getting arm-shaving sharpness in no time - please watch my video Part 2: ua-cam.com/video/tVTg0HVgoKo/v-deo.html

Vadim, excellent as always, thank you for your videos. Question - don't you always finish with the kangaroo strop? Also, is water really necessary for CBN wheels?

[@knifegrindersaustralia5158]

Kangaroo tail hanging strop removes foil and wire edge - we typically do it on a wheel with pure chromium oxide, rather than on the 'roo strop.
We often grind on coarse CBN wheels dry to speed up the process - lower the water trough and grind dry, lifting the water trough now and then to wash away the swarf; but the last fine CBN wheel must always be run in water because the edge is so fine and we want to grind it clean, not in a slurry of ground metal and CBN particles that may roughen it.

[@mitch3384]

M***********r!! I've been making my calculations based on the leather wheel being 220mm. You're right, it's 215mm.. no wonder I'm having problems.

[@knifegrindersaustralia5158]

When I realised this 5 or 6 years ago, my reaction was furious. The original Tormek's AngleMaster implies the leather wheel is 220mm, as does its name LA-220. So I think that at some point in the past Tormek silently reduced the leather wheel diameter to save on materials. After that, setting honing angle with the AngleMaster, we inevitably round the edge.

What did you charge for this one knife to be sharpened?

[@knifegrindersaustralia5158]

$25

[@johnkantar3082]

does your software have to be connected on the internet to work

[@knifegrindersaustralia5158]

Nope, no Internet connection is needed. Dozens of our customers, especially from the elder generation, who never had a PC or Mac, have bought the cheapest used Windows laptop or Android phone/tablet they could find - only to run our software on it next to their sharpening place.
Our main Tormek applet runs on Windows PC/laptop, Mac, iPhone and Android phone or tablet;
the Frontal Vertical Base applet runs on Windows PC/laptop and Mac, iPhone and Android.
