Scary sharp knife sharpener

Just watched this. Pay attention to the last bit where it rotates away from him so the blade can't be thrown at him
Looks good. Reckon I'll try one for a couple of new projects I'm working on.
He doesn't say but I reckon it needs to be bigger than the motor diameter

Might give that a go, worth a try I reckon.

That's funny, I watched this yesterday but didn't know whether to post it as it seemed gimmicky ?

Like you say....worth a try

Seen it, and it's a neat idea. The lad himself is very talented, especially considering his age!

If you have time watch his drill lathe video, it's copied plans but executed very well. Lot's of potential in the lads future.

Anyone know what polishing compound and grade etc. he is using?

(I've never used any polishing compounds, so haven't got a scoobie )

And where to buy it from.

I a lot like the honing wheel on the otherside of the tormek,

I suppose if your designing your own shape, a thin enough version could sharpen the inside of you crook knife,if you need to!

So-called polishing compounds are abrasives. Don't ever believe anyone who tries to tell you otherwise.
Yes, they scratch the surface but so finely that the unaided human eye can't see it (try a 10X magnifier as proof).

Chromium Oxide III (green color) has a nominal particle diameter of about 0.5 micron. Iron and copper oxides
(shades of brown, reds and yellows aka "rust) have nominal diameters of 0.25 - 0.4 microns, Aluminum Oxide is in that range as well.
The carrier is usually some high weight petroleum wax.

I use the Lee Valley mix of CrOx/AlOx on box card for steel edges, sweeps, adzes and flats. (Leather is really inadequate these days).
