Question about Rods for Sharpmaker

They are very useful for reprofiling.

 

They work well. I have them. I’m not an expert sharpener.
I find it easiest to use the edges of the triangles to sharpen, I find it difficult to keep a perfect angle using the flats of the stones.
With that in mind the diamond is the only way to remove metal at any reasonable rate with the stone edges.

 

You’ll need diamonds to sharpen steels like s110v or s90v.

CAN you sharpen super steels without them? Yeah... I can also walk to work instead of driving, but it’s 30 miles away.

 

I’ve been intrigued by the work sharp wit the blade grind attachment. I think I may get this instead of anything else

 

They serve the same purpose. Sal has said that the boron “adheres better to the plating” so I guess easier to manufacture.

In short, go with what’s cheaper I guess.

 

I've got both and they're the same price.
I suspect "adheres better to the plating" might mean it doesn't dislodge as easily during sharpening.
As for performance, I can't tell a difference between them. They both do well.

 

Ditto. I bought both the Diamond and Boron Nitride rods expecting a difference. There isn't.
