How to sharpen a knife
« on: October 09, 2011, 11:40:34 AM »
easy sharpening of a knife can be done with the dottom of a coffee mug the ruff ring on the dottom of the cup works well to sharpen a knife .ceramic is the next hardness to diamond. three light strokes one side three the other side should touch it up to razor sharpness

most people would probably consider that knife sharp before you whetted it. ear

I grew up watching for poisonous snakes of one kind or another so I spend a lot of time looking at the ground.  Whenever I'm around a bunch of gravel I always look for long, slender torpedo shaped sandstone, and pick them up.  They are some of the nicest quick sharpeners around and they're totally free.

I've probably mentioned it before but the ceramic tubes from the old knob and tube wiring days are great for touching up a blade. I have used cup bottoms for along time as well.

Can burnish a edge on useing a craftsman hand wrench, use it quite oftin when burnishing gravel nicks in airplane prop blades.
Another is useing steel, angle iron works and so does wire rope(Cable) under tension

The top rolled edge of a vehicle window cranked down about 2/3 of the way makes a nice, long sharpener, not unlike a long ceramic rod. (Im an old part Indian, hope that counts)

A peice of a toilet tank that is flat will get close to an edge. The new type that are glazed on the outside and still some rough on the inside. After you wori the edge down with this stone you can change to a harder glass to get a better edge. It will be similar to useing two different grades of "honeing" stones. ear

Been using plates and cups for years, but the best to me is still an old carborundum stone that belonged to my grandaddy who died in 1959.  So it is old!  It has both a coarse and a fine side.  Then I finish up with an Arkansas stone, literally.  I bought it in a store on Petit Jean Mountain in 1972.

That is what I do also but you can find sharpening rocks that will work in abandoned house sites and junk piles when in the woods.

The simplest thing for me to sharpen a knife is wet or dry sandpaper. That's mostly all that I use.
I do have a couple of kitchen knives that I sharpen on stones however.

I've tried using sandpaper, which, depending on the hardness of the surface under the paper, can yield a convex edge on a knife, but I still prefer the results obtained with stones.  It may be simply a matter of familiarity - we tend to prefer what we're used to.

Maybe its just a perception thing, but since Ive gone to water, rather than oil, my stones seem to work better. Anybody seen/ heard anything about this?
FWIW, I found a nice, flat, fine grained old 'shop' stone at a B&S shop that was filthy oily, so I soaked it with Brake Clean and rubbed off the float several times. It cleaned up quickly and well, and I started using it with water; it works great! So I did the same with my Buck stone set I got back in the '70s and have used with Buck Honing Oil since the start. Now with water they are working 'better' too.
I think that maybe the oil makes a nicer finish???, but the water lets the grain structure cut better; ie, faster??? (just like with using wet or dry sandpaper with oil vs water) Ive always heard that you cant start a stone with oil and go to water, but maybe that was a holdover from the days when they didnt have these super penetrating solvents to float the oils out.
Anyway, Ive usually got some spit, if nothing else, to wet a stone to whet an edge rather than waiting and hacking the job.

An oil stone or a water stone will keep the water or oil on the surface. Oil will usually float the cut/grind better and glaze less often.
If a dry stone glazes wash it with detergent, dry it then use it until it glazes again. ear

For stones I use Japanese water stones. They cut fast and the real fine grit ones polish the blade so that it looks like a mirror. When a blade is really polished the edge seems to last longer. I have read that the carbide crystals don't break out of the edge as much when the edge is polished and that is why the edge lasts longer.
After sharpening with a stone or sandpaper I then strop the blade on balsa that is charged with diamond spray. That really refines the edge.
