I keep the microscope base attached to the scope at all times and I put the lens of the scope right on the edge of the knife. It doesn't effect the pictures on the WEPS, but the loose base did swing a bit, making it more cumbersome to control the scope sometimes. The tighteneing of the screw for me will help tremendously when the knife is not clamped, particularly when I do my straight razor progressions.

One drawback of putting the scope right up on the edge is that you can easily chip the edge, especially as you get higher in grits.

I'll post a picture - tonight I will try to get to more of the progression.

Hey Tom, quick question... I can't seem to find any info to this effect... when going through the process of sharpening a straight razor I have found that the jump between the 1k stock diamond to the 14m pasted strops is too large... after 500 strokes per side w/ the 14m strop it has not removed any of the scratches. Which leads me to my question, what is the logical progression if I am sticking with all stock stones/strops (i.e. no chosera/shapton stones)? I just ordered the 1200/1600 ceramic stones as an "in-between" before I go to the 14m strops. Any suggestions or should I be good? Thanks for your help!

All this Sharpton & Chosera talk is confusing me. So far, here is what I've been doing. I've been progressing thru the 1000 diamond plates and then polishing with sandpaper, 1000/1500/2000/2500 grit strips temporarily taped to the plates. Then the 5/3/5 micron leather strops. I learned about the sandpaper polishing on YouTube with M0DiFiEDZ, who sharpened and polished a Kershaw Leek on a WEPS. But, I'd like to get away from the sandpaper polishing.

If I upgrade to the Chosera 5k/10k stones, let me see if I understand the progression? After going thru the diamond plates to 1000, I would move on to the ceramic paddles 1200/1600 and then on to the Chosera stones 5k/10k and then the 5/3.5 micron leather strops and finally the .5 micron diamond spray on a leather strop. Is that a logical progression for both sharpness and mirror polish?

Maybe I should wait for Tom to answer your question, but I asked the question about stone progression in another thread and, without all the confusing stuff (thus simplifying), the answer was "yes". I own the full range of WE stones (diamond 100-1000 and the ceramic stones) and recently ordered the Chosera 5K/10K stones.

As to which stropping compounds to use afterwards, I am not sure. The grit comparison chart tells us that 10K Chosera is about equivalent to 1 micron. I you strop with leather, you might want to go back to 3.5 micron diamond stuff. However, personally I do 5/3.5 micron stropping after the ceramic stones (which are the highest grit stones I now own). So maybe you can also continue with 1 micron spray on balsa. At least I am fairly certain the jump from 3.5 micron stuff to 0.5 micron stuff, both on leather, is too big.

But since the previous post also had a question about which stropping compound to use after a particular stone, perhaps Tom can enlighten us a bit on this ;). In the meantime you can find some sample progressions at Tom's blog. Look for the post on shaving with the Maestro Wu cleaver.

Thanks Mark76. I just realized that I replied to the wrong post. I should have posted in the Sharpton & Chosera The Great Debate. Oh well, I can't move my reply over to the other post so I'll just wait for Tom to reply to one or the other.

Straight razor and knife sharpening are completely different mentalities, although the same principles apply.

The default answer to any straight razor related issues is "you're using too much pressure" :) Pressure is a key component - you really need to go very lightly to keep the depth of the scratches shallow and consistent -especially at the higher grits. With pressure, you can also actually flex the edge of the edge very easily, and miss abrading it altogether.

However, I see 2 more possible reasons popping out at me before the pressure issue. The first is that the 14 micron paste is actually a little coarser than the the 1K diamond WEPS, so you are probably seeing the effects of the almost same size scratches. Secondly, the paste abrades differently than the plates - the plates are way more aggressive. But after 500+ strokes, you shouldn't have that issue with the paste.

The 1200/1600 WEPS ceramics will serve as a good in-between, but you might not need to go all the way back to 14 micron afterward (1K Japanese standard is 14~16 microns). I would suggest starting at the 5 micron or even 3.5 after the 1600 WEPS Ceramic. As you can see from the microscope pictures, the ceramics leave a very good, clean edge to work from.

One thing you may want to try on the WEPS 1K Diamond is to sweep in the opposite direction that you use the diamond paste strops on. This will give you a very clear indication of what's happening with your scratches when you switch to the leather paddles. The 1200 WEPS sweeping picture in this thread's OP shows a good example of contrasting scratches, which exposed underlying deeper scratches: here's a shameless link to the blog post. :lol:


The general rule of thumb on straights is that 8K, or 2 microns is the minimum level of refinement for a decent shave. However, I personally feel that you should at least get to the 1 micron or 15K level for a more comfortable and smoother shave.
