Just a fun video I made.

I saw your fillet knife video a while back and was blown away! Excellent video!
 
I'm not sure how Jim does it, but I keep a piece of poplar plank that I draw cut into to remove a burr. You can also "cut" the burr off by carefully running the blade (edge leading) across the stone on the side that has the burr.
 
I usually remove the burr as Omega suggests in this second method -- short, light edge-leading strokes with fine grits.

I was curious in this case because it's more difficult to remove a burr at 400 grit than finer grit stones because an SiC stone that aggressive and that course will quickly form a new burr, which is why I like to use finer stones to finish my edge.

Jim's slicing demonstration is pretty darn good, but a plump tomato doesn't offer enough resistance to a coarse or serrated edge to challenge a burr, and the burr is likely to be the sharpest edge you'll put on an edge.

I believe Jim got the burr off because he has expertise in this area, but for me the ability to completely remove a burr with a 400-grit finishing stone is more impressive than the slicing demonstration.

Sometimes I use wood also or hard plastic if needed.
 
That's s a nice knife. Phil makes the kind of knives I like! SIC stones work on HCV steels and so do diamond plates. IMO

Thanks. :)

I know they do. :D

It was just the general rumor or whatever one wants to call it that SIC doesn't work on the HVC steels and one needs to get Diamonds to sharpen them.
 
How does one go about buying a Phil Wilson knife? I've checked his site and it looks like he's not taking orders anymore. I'd love one of his fillet knives.

The best one can do is email him and see if he has anything available or see if you can get on his list.

When I sharpened Phil's V10 smoke creek I had some trouble getting a razor sharp edge using my SIC stone. I moved on to a 600 grit diamond plate and it quickly got to where I wanted it. I'm not saying SIC won't work but a diamond plate sped things up a little for me or my style of sharpening. Also, V10 is the only steel I couldn't get the sharpness level that I wanted from SIC. I have sharpened 10V and K294 at the upper hardness range and got the edges I wanted of the 400 grit SIC stone.
 
Jim's slicing demonstration is pretty cool. And obviously Jim has proven many times that SiC can sharpen any steel. But it's a complicated subject.

SiC at 400 grit is not going to shape any of the super-hard carbides, such as vanadium. The high-vanadium steels are going to be powder steels, and the vanadium carbides are going to be small and well dispersed -- maybe in the 1-5 micron range. 400-grit SiC at 40 microns won't do anything to those carbides other than rip them out or plow them aside.

So on slicing a tomato, the 400-girt SiC stone will leave a jagged edge of a high-vanadium steel with carbides poking out of the edge everywhere; it is going to work great in that application. Probably on rope, too.

In other applications, my guess is that using a very fine grit diamond stone or paste in the 2 micron to 0.5 micron range is going to refine that edge by a lot, maybe/probably (I don't know) shape the vanadium carbides along with the steel matrix, making for a better push cutter.

You mean like this... ;)
