I choose to check between grits with my USB microscope.  If there’s an angle difference, I’ll see it in the scratch pattern.

At one point, I realized that one of my 1000-grit stones was consistently about 0.016 degrees different from the others, so when I’d get to that stone, I could check with the angle cube, or even just make the appropriate…[Read more]

It’s an interesting point to note, that with each increase in grit, the distance between the rod center and the face of the stone is slightly reduced.  At least after being fully broken in.  With each step, the average diameter of the diamond particles is smaller, hence the distance is less.  The result is that the angle is reduced accordingly, as…[Read more]

Very interesting and a useful tool to be sure, but a bit overkill in my case. There are only a handful of angles I sharpen at (13, 17 and 20) and that I already have noted for each knife. If a new blade happens along, sharpies work OK and I generally like to keep it simple. Just my 2 cents.

Yes. It won’t last long but maybe with 20 degrees micro bevel it will be Ok. I will try how it works.  I’m planning to sharpen this “on the field” with 20 degree ceramic ultra fine rod thing… 😀

Thank you. Reprofiling took the longest time with the 100 grit. The wole process maybe 1+ hours.

100 – 3000 diamonds. 6, 3, & 1.5 micron lapping films. Maybe the 6 micron lapping film was contaminated or not needed, but the result looked worse than after 3000 grit.

I was not 100% happy about the result, so I stropped with 4/2 & 1/0.5 …[Read more]

Enjoy it and congrats!

Using your method (finding the angles relative to the side flats) requires that you use the internal included angles, including the one at the shoulder of the bevel.  A bevel angle of 15 degrees would have an included shoulder angle of 75 degrees, assuming that the side faces are dead-flat and parallel to one another.  Ninety plus fifteen plus 7…[Read more]

Hi Russ, welcome aboard!

Welcome 000Robert!

I’ve had that same knife at one time or another.  Note that you can clamp it higher in the vise than what your photo shows.  Anything above the flat part of the blade isn’t being held by the vise anyway.  This ought to get you a lower angle.  If it doesn’t hold properly, the top edge of the vise is probably bent.

My grit chart puts 3 micron at about 8000 grit, with 1 micron at about 15,000.  I would try using the 3 micron right after the 1000 grit stones to see if that’s a workable sequence.  If it seem to take too long to erase the 1000 grit scratches, try putting the 1600 ceramic in between.

Another possibility that’s worked for others is to switch f…[Read more]

95% isopropyl or 10% bleach solution will do the trick (I believe) but I let them “dry” instead of wiping them dry.

Thank you for the video, it is helping. This is very similar to the way Mr. Curry shows in his video.

A few years back, I had a new 800 grit stones which was taking big chunks out of the edge of my ZDP189 Delica.  On close inspection, I found a couple of clusters of diamonds which were elongated and oriented parallel to the long axis of the stone.  The particular orientation was such that it resisted all normal efforts to break the cluster f…[Read more]

I think you’re right. I wonder if it isn’t useful to temporarily use a new pair of 2200/3000 stones in place of the 800/1000 stones until they’re broken in.

There is been a slight design change to the whole cam follower and washer stack and we added two more washers to the newer units.

Welcome aboard, Robert!  As you become familiar with your WEPS, remember that there’s a wealth of knowledge here on the forum and in the “Knowledge Base” section you’ll find at the far upper right corner of the website pages.

As you become comfortable with your rig, consider being a contributing member of this forum.  There’s a regular turnover i…[Read more]

Great question. I find that the majority of knives I do allow for basic adjustments to find the sweet spot. Every now and then I do find a blade that won’t work with only back and forth adjustments. In those cases, I definitely break out my Advanced Alignment Guide and adjust the tilt of the blade as well. If you are trying to mount a knife and…[Read more]

That works just fine, as long as you keep the tape out from under the cube’s face.  It would be most valuable when mounting FFG blades in a Gen 1 vise.

I do something similar without removing the handle.  I have a machine-ground piece of steel which I can use on edge to reach in between the bolster and the vice.  It’s a little awkward to press th…[Read more]

Diamonds can also get dull.  The sharp edges tend to eventually get rounded over.  In fact very few of my old platens show a loss of diamonds, but they don’t cut very well anymore.

I’d be wary of used stones unless I was confident that there was relatively little mileage on them.  A very active user could wear out a set of stones in a year or…[Read more]
