I posted this elsewhere...and because a picture is worth many words (and perhaps many hours also), I will let the image speak.

Very nice polishing job. I hope you just use it for a mirror now because if you use it as a knife those scratches it will get will bother the s**t out of you. :D

You might be surprised how hard this knife gets used.

It does not get scratched as long as it does not contact anything harder than the ZDP. And trust me, a knife with an edge this thin does not get used for hard composites. It EATS fabric-reinforced rubber though!
 
Very cool. could you give some insight into your method of polishing?
 
Lots of time and abrasives.

It started about 6 months ago when I first reprofiled it. From that time until these images the edge was taken progressively thinner and as it went thinner, the bevel intruded further and further up the face of the blade. Somewhere around 7 degrees the bevel extended about a third of the way up the blade...so I just polished the whole thing. Let me tell you, it really glides through stuff now!

The polishing occurs the same way the reprofiling and sharpening was done...with various grits of diamond abrasives with a final polish of chromium oxide on leather, bare leather, then cotton cloth.

It is not perfect, but it was done completely free hand and by hand. It took a LOT of time, but the smile it gives me makes it worth it....and because it was/is for me, I enjoyed the process.

It was done for a specific purpose that few people will understand (slicing up tires...at times, I need to destroy a lot of tires for work...this knife excels at the task). Suffice to say, the knife is specialized to the point that it is really only good for a handful of uses (much the same way that a dragster is almost totally worthless once you leave the drag strip...but man, the ride is something!).

It is not an EDC, and use for many EDC tasks would have an ugly result.
 
Noctis, you need to get a tripod or prop your elbows on the table when you're taking pictures. That will reduce the blur.
