Looks like it will have to go in the low angle jaws if it is going to be sharpened on the WE.

No low angle accessory... The angle was about 27 dps :-) but this thing is sharpening WEIRD... Like no other steel I've sharpened before, it sharpens like ceramic knives do. The edge just keeps crumbling away and NEVER develops a burr. I am wondering if it's ceramic partly or a tungsten carbide stee l or something weird? I used diamond tape down to 3um and it has a mirror polish and shaves easily now :-) but it took forever for me to figure that out. It is slightly magnetic but not as much as normal steel... Any ideas?

Maybe it is tungsten carbide?

I'm thinking that in many paper and textile machines, they use carbide because they don't want to sharpen it very often. HSS is also common, but less wear resistant from what I understand.
en.wikipedia.org/wiki/Cemented_carbide

Tungsten carbide is incredibly hard and brittle; it is basically a ceramic powder of tungsten carbide which is bound together with a cobalt binder. (Other binders are possible, but cobalt is the most common.) So my guess is that's what you're seeing. See link above.

Not sure how to sharpen it. I have heard people got good results sharpening ceramic knives with diamond lapping films (Ken Schwartz sells some), for example the various 3M diamond films. So probably that would work for carbide as well? Here's a YouTube of Tom Blodgett shaving with a ceramic knife that was sharpened with diamond film:

We'll be offering up some diamond lapping films soon. I've used them to great effect on ceramic blades. The manufacturers of the knives at Boker and Stone River were absolutely shocked at how sharp their knives could get on the WE with diamond films.

How soon, Clay? I've been playing with making a pair of blocks using plate glass for the platens. With diamond film available, I'll need to make a few more.

If you want some right now, you can order them from Lee Valley. That's what I did. As a matter of fact, I believe these are the same film that Tom used in the video above. They do work great on ceramic knives! :-)

Bob, at Oldawan is anther source for the films and glass WEPS paddles. FYI?

A couple of years ago, I bought several sheets of diamond lapping film from Lee Valley. They were graded 15, 3, .5 and .1...I don't have the symbol mu. I cut strips and fitted them to 2 blank paddles, one grade on each side. They worked beautifully and gave some truly razor sharp edges...better than I got with the diamond paste on leather paddles. Finally I gave the remainder of the film away to my industrial arts teacher from before I retired and he used it on glass blocks to finish off his chisels.
This is great stuff and I suggest you try experimenting with it as another way to get those edges that make your eyes smart just looking at them! So you have Lee Valley, Bob Nash and soon right from Clay to get and try this wonderful stuff. So many ways to get final ultimate edges after getting a superior edge already with the WEPS up to the 1000 stones and ceramic paddles.
I don't do it anymore because in the end I am very satisfied with the real world edges I got from the WEPS using the paddles up to 1000, the ceramic paddles and the strops with diamond paste.As I get older I am more easily satisfied.

Cheers
