Does this tool where a knife edge is dragged between two angled abrasive pieces hone or sharpen?

Question

A few weeks ago I bought an awesome Global knife. I ordered this tool from Amazon:

My question: Does this tool hone the knife, or does it sharpen it?

Answer 1

This is a sharpener. Everything that pinches the blade is. It's good for returning a dull knife to reasonable sharpness, to a point where it can be honed. If you put a sharp knife in it, it will make it less sharp.

This is the type for honing.

Answer 2

As already pointed out, it's a sharpener - worse, it's probably a 20° sharpener & a Global will be a 15° blade.

When you get into good knives, be aware that you will also be paying proper money for a sharpening system, unless you want to spend 10 years of your life learning to do it manually. Don't put good knives anywhere near drag-through sharpeners of that type. See How to maintain my knife? What am I missing, and what am I doing wrong?

Füri used to make a 'TechEdge' system [very hard to find now] & whilst you can throw away the drag through sharpener, I've ever seen as good a honer as that. I've had mine 25 years & it's still in use, even though I now have a foolproof electric sharpener, the Füri is my daily honer. The bendy finger structure makes sure you just can't get the wrong angle or pressure.
[I actually went back to it a few months after my answer on the linked question above. It's more gentle than the honer in my electric system & doesn't need setting up & putting away every time.]
I have a steel, either it's rubbish or I am [I would bet on the latter].

If you do decide to go with a traditional steel, make sure you get a honing steel - they also make sharpening steels.
