Do any of you use any type of paste or polishing compound on your stone for final sharpening. I have been experimenting a little putting plain ole mothers mag wheel polish, available at any auto parts store, on my extra fine spyderco bench stone when I put the final polish on an edge. I don't believe I have ever gotten a knife as sharp, I have a laminated mora that I literally believe I could lather up and shave with and my Endura is not far behind it. I think I may of hit on something with this, Yall give it a try and let me know how it works for you. :thumbup: Chris
 
Put it on leather or MDF, NOT your stone.

Why NOT?????

EDIT: I have used a strop...a lot, with many different compounds so I am not unfamiliar with the process. I did this for the first time polishing a firearm sear and it worked so well I tried it with knife sharpening and it worked like a charm. Please explain why I should not do this. Next test is putting it on a piece of glass and trying that.
 
This may be disgusting.... BUT! Scrape the brim of your hat and you'll get some of that past your looking for!
 
rb, are you using an edge trailing stroke like you would when stropping or edge leading?

Edge leading, not a stropping motion. An added bonus, it cleans my stones better than anything I have ever tried. Rub it in your stone and then run under warm water and the stone looks brand new. Bare in mind I am only using it on fine ceramic stones, on anything else I can't say, but really don't see how it would be any benefit on a coarser stone. Chris

Interesting, I'll give it a shot. I finish all my knives on Spydie Ultra Fine ceramic with an edge leading stroke. Not sure if my knives can physically get any sharper, they all whittle hair, but can't hurt to try :thumbup:
 
Try some diamond paste on a peice of MDF after your done with the UF ceramic, your results will be even better.

I can't really see the point of putting it on the stone, I would think that if the compound is cleared from an area of the stone then you would just be sharpening on the stone again.

I have no science or reason, except that I have been putting razors edges on knives for more than a couple of years and this new method works. My suspicions are that the stone is irrelevant, it is the polish that is doing the job. That is why I am going to try a piece of glass. Chris
 
Chris, I use various grits of compounds on both leather strops, as well as a flat plank, and although I use an edge trailing method, it is a great finisher for my blades. I did put some green #6 on a hard Arkansas once, and it just seemed to fill the stone, and didn't really make any positive differences, and I was concerned about it "stacking" at the front of my edge, and degrading it. I cannot say that happened, but it wasn't any sharpening "grail" for sure. My dead flat walnut strop plank on the other hand is just crazy to use. A dab of mineral oil, and a good coating of compound, and my edges are slick, sharp, and scary. Good luck

Oh yeah, nice piggie you stuck too!
 
Runningboar,

I've given a quick try to your polishing method with a liquid product used to clean the copper coating of traditional pans applied on a high grit ceramic stone (a worn DC4 Fallkniven). I'm surprised to get such a result with so few strokes (i did it quickly, just for a try). As mentionned, it cleaned my stone in the same time. Thanks for sharing.

Runningboar, I have the ceramic stones too, but I would think the compound on a glass plate would be even better. Plus there would be no chance of damage to the ceramic from the abrasive in the compound...just a thought. I'll have to experiment with the glass myself, neat idea :-)
 
Makes sense to me, after all it's a polishing compound. I agree you likely don't need a stone, I'm sure glass would work just as well.

i have tried it on glass and leather
i found it worked better if you put the mothers paste on either a sheet of paper or the paper medical tape, stuck to the glass
seems to work well for me

will have to give it a go on the spydie stone though, see what it does
