So these mugs were both stocking stuffers from the wife from Xmas. We have big stockings.

So, the left mug is about the same as dark sharpmaker stones. The right mug is a nice 400-600 grit that worms about twice as fast as corners of the same coarse sm sticks. Extremely effective . I also used it for my crk and our kitchen set today.

With these any my strop I have results comparable to anything else I've tried and faster than the sm. Of coarse I use the sm a lot. But a nice coarse cup really works

Thoughts ? Anybody else do this. You can have a three grit set up if u have a cup assortment.

I haven't done it because I couldn't feel a coffee mug and make an accurate guess as of the courseness comparison to stones so I worry id mess up my edge.

do you use the rim?

my buddy did maintenance for the city for a while and collected dead lights from street lamps, those are incredible sharpening tools
 
Yup. The bottom rim has the surface you need just like in the picture. Its not aggressive enough to do damage. But faster that a sharpmaker which can save u a lot of time. I will be doing this often. I can free hand so this is super eaSy for me. Just watch your edge with a marker if u need.
 
I use a large chunk of porcelain from toilet tank, it sharpens well and on new/slightly used knifes you really can't tell they were ever sharpened.

It's great for touch ups or just general care of edc blades.
 
I have a nice 3 mug setup at work with three different grits. :). Starbucks mug is the fine grit. I strop on a piece of paperboard from a pallet corner protector with some green compound on it.
 
I read the title, and the first think I thought of was that scene in Chronicles of Riddick.

Nice. I'm sure you have great results.
 
I like to use the underside of a ceramic baking dish or a ceramic casserole dish as my "coarse" since they are often of a less fine construction, particulate wise.

If you couldn't tell, yes, I do this as well.

I have also been known to use the top of a car window in a pinch.
 
Very nice. I forgot about the window trick. Great tip for the road or field.
 
Also, the casserole dish allows for a longer sweep if using a chef or otherwise longer bladed knife while allowing forease with angle maintenance since it isn't on a circular surface.
 
New mugs work the best, the older they are the more the bottoms get polished on your countertops. Stuff we use seldom work best - ramekins and seldom used bowls are the best in my kitchen. I'll grind it a bit on the bottom, then 'steel' it on the glazed rim. I have not much luck on modern sport cutlery, but on lower RC stainless I get very good results.
 
40 years ago, it was the rage in the Knife community to find old electric pole insulators at flea markets and swap meets, and use those for sharpening.
Going back years further, every 'Deli Counter' clerk sharpened his knives by holding them flat against the inside curve of a 1gal ceramic pickle jug and running the blade around the jar. This 'may' have been the very first 'guided system!'

I get requests for those all the time. No telling how many hundreds I've salvaged.
 
I do it some times if I don't want to pull out my Stones or Crock sticks.

I read about first in Backwoods Magazine.
 
As much as I love the coffee mugs, I've found something better!!!

Having moved from Maryland to Texas this past November, we left behind a lot of things. The kitchen stuff like plates, bowls and saucers were heavy and worn, so they were donated to the local thrift shop. On arriving in Texas and buying a home, we found great stuff right down the round at IKEA. We bought a service set for 6 for a very reasonable price, and getting home I found the bottom rim of the soup bowls to have a great unglazed ceramic ring about the same grit as my old "carborundum" stone. Same with the plates. I cut open a lot of cardboard moving boxes and broke down the same for the recycle bin, so I had a knife or two that needed sharpening. The IKEA bowls did an outstanding job!!!

The heck with stones, just go get a soup bowl or two at IKEA! Then you have a dual use item; eat your chill out of it, then sharpen your knife. And their microwave usable.
:D
 
Those are actually jumbo mugs. Like almost four inches .
I need to try a soup bowl next.
