carbide sharpeners any good?

[joneb]

I have not used this type of sharpener, are these any good for knives? https://www.sharpensbest.com/sharpnspark

This looks good for rough sharpening of yard tools,https://www.amazon.com/Corona-Sharp...&qid=1528064149&sr=8-1&keywords=sharp+n+spark

A tool like that can be used to put a "utility edge" on a knife. It will make the knife sharp enough to cut.

I'd be pretty upset if anyone used something like that on any of my knives.

That's what I thought, I use old carbide planer blades from a hand power planer to spark ferro rods and do rough sharpening of camping tools. Its light weight and works well. But these blades are not at a 90 Degree angle.

I wouldn't use it.
