Sharpening a ceramic swivel knife

[YinTx]

If you find his facebook page, I think they list a phone number there for him.  I have found that to be the best way for me to reach him.

Also, I put it to use, many times since the last post.  It is phenomenal, I love it.  Still pick up my old Tandy on occasion, but I do enjoy using my Robert Beard swivel knife.

Of ceramic knives, yes they are brittle, drop it once or hit something hard it may become useless. Only a very fine diamond hone will sharpen ceramic however you may find a leather strop on a piece of wood with compound could remove unseen micro particles of  leather or paper material stuck to the ridges. The original ceramic kitchen knives were undetectable by airport XRAY machines so they required them to have metal particles in the material. Your blade may not have them and I do not know the year this change came about.

I must say my experience differed from yours.  I did manage to sharpen mine with a high quality sand paper.  Just takes some patience.

Thanks, I was going by the best of kitchen cutlery like the Kyocera  Company brand which is more for cutting produce. The swivel knife may be made of a lot different materiel and I assume you meant wet or dry auto body sand paper and not flint sand paper for wood?

Yes, and with a lubricant (soapy water).  Takes some time and diligence, but it'll get er done.  Much smaller surface area to polish vs. a kitchen knife, too, so that helps.

Basically: is it necessary?

I keep seeing people on youtube and whatnot stropping their ceramic blades before use, but I've been using the same ceramic filigree blade for all the work I do for... eight years now? Haven't stropped or sharpened it once, and the only time I notice it dragging is when the leather is cheap and spongy and/or badly cased. Would I be getting better results if I did? Or are the youtubers stropping unnecessarily?

Bought mine in 93. Still use them. Never stropped neither.

seek out a Swivel Knife Blade Sharpening Guide 8126

it will take the guess work out of keeping your blade sharp.

 

you mentioned you did not know which rouge to use

I like the green or the white.. either is fine.

Same here, Same year. Bought two. Only used one. Still have the other, as well as The extra needle for my badger airbrush gun. I’ve never used the extra of either. Never had to strop or “sharpen”, and it’s never chipped on me. Crazy, when you take care of stuff it last, like the edge of a ceramic blade…….

Use a high quality 3m paper if you can.

3M, at one time, made opthalmic sandpaper for use in polishing lenses for glasses, etc.  Maybe you can score some online somewhere.
