Thanks for the replies guys! Since this was posted last year, I have actually changed up my methods and techniques since then. I no longer use my Wicked Edge and an actually going to try to sell it soon. I've once again started to free hand again.

Here's my findings in a great all around edge this far:

I distress the edge by grinding a flat on the edge if needed. Then I reprofile if needed on my Shapton Glass 220 until the flat is gone, without creating a burr. I'll alternate strokes until I'm satisfied, which is normally about 20 or so LIGHT strokes. I repeat until I stop at around 1,000 grit Shapton Glass. The finish on very few, light stokes on Strop mans black compound, then red, the blue. (Making the switch to Ken Schwartz PolyChristalline sprays on nano cloth soon).

I'm going to cut for a moment and explain why I've come to appreciate a well done 1k edge.

I did this experiment I call "5 days of sharp." Each day I would finish off my Spyderco Tenacious edge with a stone, starting at 220 one day, 500 the next, then, 1,000, then 2,000, lastly 4,000. And each day get a feel of how the edge reacts to daily things I cut.

I noticed that 1k, even though not very reflective, just cut so well. Push and draw cuts. The edge is exactly how I want it. Sticky. SO sticky. If you go to feel for sharpness it grabs you immediately. A scary feeling B)

A lot of this comes down to technique though, I can shave off of my 220 if I did it right. The 1k edge is not super aggressive but it gets into the crazy levels of sharpness once I'm done stropping. (Hair whittling ect...) The finish is a lightly reflective, fine, even satin finish. Very attractive :).

Currently I've been playing around in the 1k to 4k realm to see how I like it.

I have found that for a knife to cut line easily and for instance plastic surrounding processed ham I use a King 800 grit stone I got the massive version it weight 4KG it muds up quickly and can hollow but what I do now rather than flattening I find the high spots and work on those to level the stone (in fact I have never flattened it with any flattening stone and I even keep the mud dried out and although I have not used it yet it can be used for polishing or cleaning a knife or sprinkling onto a stone.Its too good to pour down the drain) and work on those areas this way I have not needed to flatten it and the stone is reasonable flat .
With these utility blades I hone them on the stone as well if I want something more refined I hone on a 4/5K I have 1 10K & a 16K that I use one razors or hairdressing scissors since it is easy to convex them by hand.When I finish I the shears and the razor I do a couple of passes on a leather strop with some CBN spray but I probable do 2/3 light passes each side and that is it . The sharpening of razors & hair shears I do almost entirely with edge trailing strokes I only do a back and forth motion if they need changes or repairs.

leo you gotta start doing some youtube videos man... your a beast! I definitely think you have the most versatile set-up around here anyway, which is good. sharpening should never be done through a single approach every time! :silly:

Thank you!
At the moment i do not have anything to film with other than an iPhone or iPad and secondly I have a way to go to compare with the likes of Jon from Japanese Knife Imports or the legendary Murray Carter .
I have picked up a lot over the last couple of years but the more I discover the more I realise I have to learn .
My biggest medium of sharpening to master at the moment is ceramics those knives from the other day inspite of doing by hand were still not great so in the end I put them on my Edge Pro with the special diamond stone 1200grit I did not finish them on diamond tape 3K which maybe I should have but i did not want the edge too polished . The end result was in my mind just acceptable if I rate a steel knife I have sharpened on a scale of 1-10 I would say my best sharpening is just under 7 and I would say the ceramics were just over 4 this is a scale that Murray Carter uses He rates a blade he can shave with by his standards as a 7 so I am probable marking my results a little high.
I must admit to doing more & more freehand sharpening it is way more satisfying and is quicker one frustration I have found with thew WE is occasionally the stone guides have slipped whist I have been sharpening on both occasions this has happened I have not noticed until near the end . Also with the bench stones there is no setting up it is straight in .
The Edge pro that I finished off the ceramics on is quite tiring to use since the small blades have to be kept flat on the table and the ball on the stone arm bruises my palm especially when I was doing 400 passes per side working from Atoma 140-400-600- the Edge Pro fine diamond stone .
I think if I try doing another ceramic i will do them by hand but intentionally convex the blade raising the spine slighty on each pass since this give a much easier edge to achieve since it is unlikely that I raise the spine too much it maybe that on some passes the spine is not raised enough but this technique seem more forgiving and I have had better results on ceramics using this technique I tried to be more precise on these and this I think is counter productive at least at my skill level on ceramics since it take much longer for a visible image of the bevel to show up where as on steel 5 passes is enough to see a difference and if it is wrong it is easy to correct .

Whilst on the subject of ceramics and belt grinders Ken suggests using plain linen belts and then using his potions on the belts so diamond / CBNs sprays or pastes this is probable the way ahead to sharpen them cost effectively .
My own pride is to master doing them by hand but if it is for a paying customer the linen belts with Ken's sprays seems to be the way ahead.

Totally agree, Josh...

You're a beast, Leo! I would love to see you in action...


I love this forum -- there are so many beasts-masters here. I have learned from every video I've watched.

To see someone take a specific knife, show how they place & position it in the vise and the progression is a "master class" that transcends space.... we don't have to be in the same room at the same time for "masters" to impart lessons to "apprentices".

And, because they are archived in the forum or on youtube, they also transcend time...

Sometimes the lessons are small sometimes major breakthroughs.

I, personally, could really see the value in having an available library of Wicked Edge Certified Master Series of training/education videos.

"Virtually", and really, working together to improve our skills...

For Now,

I also really like the fact that discussion of any sharpening method is allowed, even if it is a rival product. I love, I mean love, my WE and will never be without one. But I have a lot of convex edge knives and Japanese knives that I prefer to sharpen by hand. I have learned a lot in my few months on this forum and, for better or for worse, have been sharpening knives for over 40 years (started young ;-)
