Only if you strop on 36 grit ceramic sandpaper! 😁

I'm not aware of any knives made from tungsten carbide, but it is extrremely hard and tough, so you would need diamonds.

I believe Sandrin *only* formulates their proprietary tungsten blades to hit around 71 hrc, so definitely capable of being sharpened on diamonds. Personally I'd try to do it with an extra fine plate or a bonded diamond stone to minimize the chances of chipping. I'd also stick to edge trailing strokes for the same reason.
 
I used diamond spray and a wooden strop to bring my Sandrin back to shaving sharp. It took a LOT of cardboard to even begin to dull it though. Honestly, I'm still a little worried about truly sharpening it. I'm not the best at freehand sharpening just yet, and I'm not too keen on throwing it on the Edge Pro just yet. With how rarely it needs to be sharpened, I'll probably send it out to a pro if/when it needs to be reprofiled or something.

I'm sure WValtakis WValtakis , REK Knives REK Knives , Gary W. Graley Gary W. Graley , or any number of the highly skilled sharpeners could help you out with that if you decide to go that route.

I'm thinking that's what I'll do thanks again all!
 
Usually one of the biggest issues with sharpening carbide is that it's brittle, so overly coarse diamond on a rigid backing like diamond plates will cause the edge to micro-chip. You have to go fairly fine with it, which means fairly slow removal rate if sharpening manually.

Hey, I just picked up Sandrin Torino in tungsten carbide. Sandrin recommends using diamond lapping film.
see video:

PS: I am interested in sharpening the knife. (I use a TSPROF with Edgepro Matrix stones and lapping film) Send a PM to me if you would like the blade sharpened free of charge.
