I've got the same set up, ceramic and a set of imbedded steel or something that fits the hole. 30 yrs old, I use lansky on a couple knives that thats all they see.
But what I bought thats the same as the ceramic rods is the Smiths at wallymartinez for about 3 bucks, it's the ceramic rods held in place by a plast housing, you could put it in your pocket if need be.
I have one in every glove box, knife drawer and go bag.
They make a few different models, one has the angled carbides on one side and ceramic on the other, one does fish hooks.
For the money you all should check these out, there so easy the wife can or would be willing to use it in the kitchen.
Make great gifts, cheap.
field dressing big game and a quick touch up I want something I can use with cold hands and not lose anything in snow, and still be precise. This is it for the field,
