most interesting setup .... I've seen pictures of such sharpening systems but never touched one ... at first glance it sure looks complicated

]My Norway and Finland knives have a different cutting angle than American blades. Be careful using sharpening machines which may not match your edge angles.

I've just replaced my Lansky set that I have worn out the stones on. This type works best for me to keep the angle exact, especially if I am sharpening a knife the first time. Once I go through the complete set of stones the knife is dangerous sharp. Once there, I tend to just use a small set of ceramic sticks to clean up the edge back to razor sharp. I built a hunting knife from a blade blank back in 2002 that I've used for skinning and quartering in the field and it has been sharpened once on the Lansky stones, but touched up many times with the ceramic sticks. I am careful with it around the bones but it is always crazy sharp once I touch it up again.

UPDATE =====

I'm still using the same set of Smith's Sharpening Stones discussed earlier in this thread .... in fact, as shown below, I used ours for a couple of hours or so this morning sharpening a variety of blades .... all of the blades are made out of really good steel .... 2 folding knives were made by Buck - 1 fillet knive by Schrade Walden - 1 utility knife by Leatherman - the rest were made by Imarku chef's knives .... I've never measured the sharpening angle of the edge I try to put on a blade .... since I sharpen by free hand I'd be surprised if any two come out the same .... the cleaver's angle is a bit higher than the rest and its the only one in the picture that will not give a smooth shave .... there is absolutely no telling how many hours of sharpening a fairly wide variety blades that this Smith's stones have taken care of .... unless something totally unexpected happens, it should last much longer than my lifetime

As for sharpening, I've been using a DMT diamond sharpener and just ordered a BeaverCraft honing strop. That will really put an edge on my knives.

I have two wicked edge set ups; my original is their table top version. I use it primarily on knives that need a less than 13 degree sharpening angle. (i don't have many of those left)

The one I use most often is my pro model. It allows for quicker transitions and makes sharpening down to .01 microns quite rewarding and fun.

Here is the process i use when sharpening my pocket knives. This was taken about 2 years ago now.

The station,
Image
Mounting the knife
Image
Determining the angle using black sharpie, 1000grit stone and magnetic angle finder.
Image
With sharpie on the blade edge
Image
Image
Micro scope taking photos of the edge.
Image

Finished edge, you can see some scratch feathering near the Choil. That is mostly due to the angle difference in the blade there. I could spend hours bringing that angle to match the rest of the blade, but I'm not that picky
Image
Image

Now here is what the process looks like under micro scope.
Starting grind, 100 or 200 grit stones, its been so long i don't remember. THe key is to make the edge have uniform and even scratching.
Image
Image

Here is a bit later, you can see how the edge develops a saw tooth pattern as you work it with finer grit stones. Towards the left and right edges you can see a bit of a burr formed on the edge. (The dark area at the top of the edge) If you notice from the first photos i have a wine cork. I run that cork along the edges and it pulls those burrs free of the blade.
Image
Image

Finer grit stones working those deeper scratches out.
Image
Image

Here i am after going from 100 grit to 1000. I've now started on polishing papers, This is probably 30 to 10 micron papers. again at the top edge you can see a burr forming, (if you don't have a burr, you won't have a sharp knife.) The burr is that now bright line. It gets removed between each new grit of paper, or diamond paste on balsa/leather.
Image
Image

Final stages of the work, leather and balsa with diamond paste down to .01 microns.

Image
Image
Image
The edge is that mirrored black line at the top of the blade. the little dots on the edge are from an alcohol wipe (to get the diamond paste off.)

Holy smokes, I sharpen mine on a little stone on my knee. That's quite the setup.

FURTHER UPDATE =====

its cold and rainy .... so, I just finished sharpening 20 some knives .. :D .. many are shown in the quoted post above .... a couple of years ago when researching chef's knives I found that as is the case with every other cutting edge I'm aware of, answers as to the optimum sharpening angle will vary widely .... that is most certainly true for chef's knives ..... bottom line, 5 to 10 degrees with the closer to 5 the better is what I settled on ..... as I've noted repeatedly over time, I still use sharpening stones on my Buck belt, sheath, folding, and pocket hunting, work and general use knives .... I've learned (the hard way) that changing my grip so as to come out anywhere near 5 degrees ain't easy .... rather, it just ain't gonna happen .... back in late December of 2022, once again following a good bit of research, I swallowed some long held prejudices and ordered an "Orange Ninja 4-Stage Knife Sharpener" that I believed is designed for sharpening chef's knives .... https://www.amazon.com/dp/B09PZDXSLL?ps ... yp_imgToDp .... I'm happy to say that has proven to be a good decision .... I've used it hard and it consistently turns out very sharp edges .... that being said, for me it is a special use sharpener that will only be used with chef knives

Jim,
Thanks for resurrecting this thread again. The last two days I have been hopelessly trying to sharpen a few knives. So far, the Spyderco sharpmaker is my most consistent performer. It' puts on a good edge when I do what I should.

I also dug out my Edge Pro Apex kit that I never really knew how to use. It was too expensive to toss. I got a few good edges on a couple of small Case Finn sheath knives so far. I'm still learning this one.
