Sharpening

I guess this is what he managed to pull out from all those sharpening tutorials he wrote he watched on Youtube.
He could put a coin or two on the stone or screw washers or whatever to help him define and maintain the sharpening angle.
So what is my point?
Advice like: ''Watch sharpening videos on Youtube'' does not work for everybody.

By the way;
if sharpening speed is also important for the starter of this thread...
NeevesKnives has a new video how to sharpen a knife if you are in a hurry.
Outdoors55 has also a video, how to sharpen an EDC knife in 90 seconds (one DMT plate and strop).

Some youtube videos are a bit rubbish, but he wasn't paying attention if he was watching any of the many good ones out there.

But you're right. Some people don't learn very well watching a video or watching someone else do something. Some hand/eye coordination and ability to translate instructions/tutorials to your own practical way of thinking are prerequisites to succeeding with things like this.
 
Thank you very much Cudgee.

Eye or pivot holder is precision Festo cylinder SLT-10-50-A-CC-B with ball bearing cage guide.
I added M4 rod for angle adjustment - one turn is 0.7mm …. more then enough precision for fine angle adjustment.
The rod for stones/files holder is precision hydraulic pipe with 8mm outer diameter and the eye/pivot is Elges Germany with 17mm diameter hole.
Why 17mm eye if the rod is 8mm? To gain more horizontal angle (left-right) for sharpening longer knives. I made a guide bushing to reduce the diameter of the eye hole from 17mm to 8mm to fit my rod diameter.

The knife clamps are from eBay ($18). They are very similar as clamps on KME sharpening system but my clamps have M3 screw in the middle so you can tighten them without a problem and the knife won't move in the clamps no matter what.

Once again great work. Thanks for posting, i like your thinking. :thumbsup: :thumbsup: :thumbsup:
 
Just in case if someone will say I'm using 'sharpening crutches' ....
Here they are.... big diamond sharpening plates glued to beech plywood. They were $5 a piece (or so) and they cut like... well, like diamond plates.... for about 3 years.
Yes, I can also sharpen my knives on those big plates but for my EDCs I like more my modified folding sharpener.

Here they are:

They are 7 inches long, 3 inches wide and 1 milimeter thick steel plates electroplated with diamonds.
That's why I put them on plywood. I could made aluminium base plates but plywood works just fine for what I use them.
The description does not say if diamond are polycrystal ol monocrystal but the plates are working just fine. They cut wahtever steel I put on them.
I got them from eBay and the cost was $15 or $17 for those three plates.

By the way; I was looking at 91bravo photo of his diamond files on plastic handles…
Hehe;
let me show you a photo of my second prototype knife sharpener:

Looks like this thread is converting to: '' Hey everyone, look all my sharpening gear! '' 🤭

I wonder if the starter of this thread decided what to get or use to achieve his goal.

True.
The OP was last here Saturday morning. Since he wanted something " simple and quick", he may have lost interest by now.
 
They say there is no free ride.
If "I hate sharpening" + "fast" + "simple" are deciding factors I would just take my knives to a professional sharpener.
As simple as that.

I'm the "starter". Once down this rabbit hole can you ever reach your objective? I think that the objective changes a bit as I learn. I'm 78, have been using and sharpening (badly) for about 70 years and I'm finding that there is a lot to learn. I got a Work Sharp Precision Adjust and am learning to use it on a Kizer Drop Bear (because it has a simple blade). I Enjoyed reading Steven Roman's book "A Primer on Folding Knives" so that I could be confident about the basics. Now I'm a bit "stuck" on the finer points (i.e. beyond 600 grit). It would be helpful if someone could provide a SIMPLE explanation for the ceramic stone and where it belongs in the grit universe.
 
One thing that Americans are very good at doing is "overdoing". That applies to knife sharpening as much as anything else and I have no problem with that. However, I'm at the beginning of this journey but I don't have decades to perfect freehand sharpening, so I decided to keep it simple. I think the Work Sharp Precision Adjust is a good start. I am able to generate a consistent bevel and begin to learn what constitutes a good edge. Then I can take it as far as I want. Currently I'm a bit stuck between the Work Sharp 600 grit and the ceramic hone. It seems to me that I need some intermediate stones but haven't yet concluded what that should be. Cost is a big consideration. Wife doesn't understand why I NEED all those knives :rolleyes:.
 
I don't have any ceramic stones because I can't find any use of them. As I understand they are used to refine the edge at the end of the sharpening process. I also could be wrong.
One thing I know for sure; those ceramic stones/hones are not good to be used on high carbide steels like s110v, s90v, maxamet, K390 and similar. Those stones do not cut carbides but crush them and make microscopic cracks in the edge of the knife.
If someone is interested I can attach the link to the article with high magnification photos.

Regarding Work Sharp Precision Adjust;
I was just looking at photos of the sharpener. I have no idea if you can get additional stones with finer grits. If that was me I would just make a new stone holder and buy a set of cheap diamond stones if I would want finer grit then #600. But that's me.

What can I say about finer grit then #600;
For my sharpening system I have:
-diamond stones: #8o, #120, #180, #240, #320, #400, #600, #800, #1200, #2000, #3000
-one water stone #3000
-leather strops with: 0.5, 3, 7, 15 and 30 micron diamond compound
I have done a few polished edges but I didn't like them. I made my PF719 (12c27 steel) hair whittling but found no use of such edge.

I could also add about the sharpening speed…
After my DIY experiment with folding pocket sharpener I discovered it gives me the fastest sharpening speed of all sharpening methods I have in the house. I can sharpen any EDC or Opinel I have on this sharpener in a few minutes. It's small, light and always available on the shelf of my living room. I can also take it with me wherever I go.

How do I sharpen my knives lately:
-Kitchen knives: #240 diamond stone and strop with 7 micron diamond compound
-EDC knives: #240 or #320 diamond stone and strop with 7 micron diamond compound
