Finally I put a 17° micro bevel on the blade with the 5k Chosera stones. This knife is going to get used, ostensibly for deboning meat, so a slightly toothy, slightly wider micro bevel will be just the thing:

and then I did about 20 strokes per side with the 3.5 micron strops to put a final touch on the edge. I hope Krystina's customer likes it:

I'd love to hear everyone's thoughts.

More evidence of what Tom often describes: starting with the 1 micron boron nitride phase, a small dot becomes visible in the middle of the blade about 2/3 of the bevel from the edge. As I continued to polish the bevel, this dot becomes more and more visible, incrementally revealed with each progressive grit. Each step is essentially pealing back the layers of light scattering so we can see the dot better. The same is true of scratches and that is why we suddenly see scratches as we get into the higher grits.

On the next knife I do, I'll use the stock diamond stones and ceramics before proceeding to the strops.

Excellent, Excellent, Excellent!!!!!! Thank you Clay!:woohoo: :woohoo: :woohoo: :woohoo:

It almost looks as if the .25 and .125 cause more damage, when in reality, they expose everything underneath.

One thing we need to be careful of is all the crisscrossing. I think this is the most difficult type of scratches to remove, and again, at the .25 and especially the .125 levels, it makes everything look "bad".

One thing Clay or I have not really mentioned is just how sharp these knives really are despite their ugliness under the scope. Sharp is a given.

WHOA Clay! That reveals tons of info I don't think we ever would have had without looking at the edge on a micron level! That's wild how the 1 micron diamond paste seemed to polish better than even the .125 CBN spray! That may very well cut out a lot of time on the end polishing of edges for some of us =)I still don't understand how the 14m paste still seemed to be more refined/higher polished than the 10k chosera (form looking at the pics), that is weird! So I have a few questions...

1. How did you get the microscope to the same position each time!? lol, with the stand?
2. How many strokes did you do on average per side on each grit?
3. Could you explain a little more about the different types of leather grains? (i.e. full, top, and split grain)... I actually purchased this and re-stropped my paddles with the rough side out... what kind of effect do you think this will have? I noticed that the WE strops are smooth side out, but everything I've read on forums seems to imply that the rough side should be facing out so it will hold the stropping compound better... what are your thoughts?

Here are a few pics of the leather in the link above... it is supposed to just be cowhide tooling leather... what do you think?

that is what i'm REALLY interested in... basically b/c that's what I have is stock everything at this point (althoug my 5k/10k chosera's are coming in tomorrow! lol)... What does the jump from the 1600 ceramic to pasted strops look like? VERY interested to find out!!

Hey, thanks for spending all the time doing this for us... It means a lot that the owner of WE would take the time to do this for his customers. I also know how much time this probably took... Thanks again!!!

So you think that's what it is Tom? Just the finer micron grit revealing deeper scratches that were already there? Could it not be some cross-contamination or something? I think one thing you could do to be able and tell would be to go to plain leather at that specific stage and see if it clears out the valley that may have had metal pushed into it... what do you think?
