Sharpening with Paper Wheels

I've read it myself some time ago, but it is indeed interesting reading material for people interested in sharpening with Paper Wheels.
Guess who Vadim got the idea of using Paper Wheels with diamond compound from ? ;)

Ok... :)


I understand...


By the way... did you receive my email I sent some days ago?

Cheers

In this short article is no definition of BESS and what compound was used on either wheel.
Is it in some of the linked studies?
 
Italian made A.G.A Campolin Maltese stiletto from a collector.
The knife was recently bought brand new from a foreign shop, but it came with quite a lot of blade play, a very rough ~55 degrees inclusive "edge" with a big burr still attached to it, and no point at all.
Also both sides of the blade aren't mirror images of each other, with a center ridge that is off a bit on one side.
Anyway, especially the lack of a point bothered the owner, the bad edge came in second, and fixing the blade play will probably be a job for another day.
This is how the knife looked before resharpening:










And how the knife looks now.
While keeping the edge angle about the same so the bevels would not widen too much per owner's request, i resharpened the main edge completely and the bayonet grind only superficially to come to a sharp point with a 15 micron diamond compound Paper Wheel, then cleaned up the bevels a bit and removed the tiny burr with a 1.0 micron diamond compound Paper Wheel.
The edge angle again measures ~55 degrees inclusive, yet the new apex is just sharp enough to shave the hair on the back of my hand a bit on skin level.

The first owner of this small Sebenza apparently thought it a good idea to use the knife for sharpening practice in his new Wicked Edge.
The outcome made him sell the knife for a measly 150 Euro's to owner number two, who sent it to me with the request to tidy things up a bit and give it a bit of a shiny edge.

Below is what the knife looked like when i received it, still with it's very rough and partly unapexed "edge", and with an edge angle of ~40 degrees inclusive at the straight part of the edge, changing into ~45 degrees inclusive from belly to point.











 
After reprofiling & sharpening on a Paper Wheel with 15 micron diamond compound, then deburring and polishing it a bit with a second Paper Wheel coated with 1.0 micron diamond compound.
The new edge is a bit convex, and measures ~30 degrees inclusive on the straight part of the edge, changing into ~35 degrees inclusive from belly to point.
This to avoid widening the bevels there too much, as this blade is relatively thick behind the edge in that area.
The last picture shows a small facet at the heel which has an entirely different angle, so i could not remove it without making things worse.
Visually it's not perfect yet treetopping sharp, and the owner was happy.

User LH Sebenza Micarta with it's blade made from Devin Thomas stainless basketweave damascus (AEB-L and 304)
Reprofiled & sharpened the old slightly convex edge with it's apex @ ~40 degrees inclusive into a new slightly convex edge with an apex @ ~30 degrees inclusive on a Paper Wheel with 15 micron diamond compound, then removed the extremely fine burr on a piece of copypaper with a dab of 0.25 micron diamond paste.
The new apex is reverse chest hair whittling sharp and the new point is also quite close to being centered.
To my functioning eye the bevels look near-mirror like, but the camera sees a bit blotchy scratch pattern due to the different layers in the damascus steel.

For people using diamond compounds on Paper Wheels like i do; give Nano-Oil 5 weight a try.
I have been using this oil exclusively for quite a few years now, and so far it's the best i've come across.
It remains speculation if that is because of the special "fullerene" additives or something else entirely, but it seems to make the diamond particles cut cleaner than anything else i've experimented with.
Certain steels like ZDP-189 and S35VN come off the 15 micron diamond compound wheel completely burr-free and ready to use, which is something i've never been able to do with any other oil type.

Awesome ongoing thread, keep it up!
The other day Vadim notified me that the German version of his Knife Deburring Book (6th edition 2021) is available for download, so I grabbed it.

Do you have the 6th edition book (in English) too?

I might pick up paper wheel sharpening too, looks very effective!
 
An older one, a user Spyderco Military in S90V steel from a Dutch forum member who requested a little more bling.
First i used a standard Paper Wheel with silicon carbide grit, followed by a second Paper Wheel with 15 micron diamond paste as well as a third Paper Wheel with 6 micron diamond paste, after which the tiny burr was removed on the Tormek leather wheel.
It's not a true mirror edge, as with the magnifying glass in my Victorinox SwissChamp i can still see fine scratching, but with the naked eye it's close.
Sharpness is hairwhittling (both to and from the root) and it can also slice single layer toiletpaper with ease.






 
I first talked to Wootz/Vadim when he joined this thread on Paper Wheels on the Australian Bladeforums in 2015/2016:

https://www.australianbladeforums.i...ay/general-blade-discussion/sharpening/24864-

Vadim was very interested in the modifications i had developed to the Paper Wheels sharpening & deburring system, and which transformed the sharpening/polishing of ceramic knives and later also high (vanadium-) carbide steel types.
Those mods involved the use of various fine diamond compounds together with certain types of dried oil to make the diamonds adhere to the Paper Wheel surface.
Vadim adopted my process to aid in his growing knife sharpening business in Australia (as did quite a few other knife people around the world), and we kept in contact over the years from time to time.

It's very sad that he departed this earth at such a relatively young age.
My impression is that if he had lived longer he would have advanced the knowledge of knife sharpening even more than he already did in the time that he had.

He never told me this in our e-mail conversations, but i recently found that he mentions me by name in the on-screen text, :)
