Rolling knife sharpeners - how useful are they?

[SUP]

I just saw a rolling knife sharpener on Amazon for the first time. I wonder how effective they are.

Has anyone here used one?

Are you talking about something similar to the jigs sold for sharpening swivel knife blades, or something else?

[fredk]

If its the type I'm thinking of, they put the knife at a fixed angle which is not always the best angle for our leather working tools

For straight straight knives they work better than nothing but barely. No real way to use them on a round knife. If you are doing a kitchen knife that gets beat to hell by a spouse that has no concept of a cutting board or slicing action, probably OK. A good knife you hide from that person - use a few finer grits on progression and a strop, or just a strop.

Sorry all, was away for a few hours so could not answer your questions.

Will post a pic shortly.

@Mablung, I've not seen a jig to sharpen swivel knives, but I don't think this is it.

I mean this one. I believe it can hold the knife so that the blade can be sharpened at 15 degrees or 20 degrees.

@fredk   I think you are talking about the same one. I agree, Only 15 degrees or 20 degrees and the knife held at one particular angle will not be of much use for our leather working tools  but since I saw it for the first time today, I wondered if it has any use at all. Like @bruce johnson says, for straight blades used in kitchens, maybe. It would be a bit awkward to use too, I thought.

Good to know about anything new anyway. Thank you all.

Well... many schools of though on knife sharpening. Rabbit hole as deep as night.

As for me.... freehand. Dry stone. Arkansas. Final strop on paper, leather or blue jeans (depending what's handy). Shaving sharp.

Handmade - ground from a sawzall blade, cedar handles. I use it occasionally - sharpening it as above. Otherwise -- utility knives

And that Tumbler looks like a sweet rig, I must say.

@NatesLeatherGds, No idea how it is. Maybe someone who has actually used one will talk about it here.
