  Ceramic knife sharpening
Posted by: SHARPCO - 02-16-2019, 12:40 PM - Forum: All About Edges - Replies (5)

A few days ago, I sharpened a ceramic knife and failed. 

I tried it with Tormek & CBN wheels(400 & 1000 grit) then honing it with leather belt loaded with PA-70(Tormek honing compound, Aluminum oxide).

But I got 300 BESS. 

What did I do wrong?

Thanks to Subwoofer for putting this together. Another great edge sharpness contest in the UK.

Sharpest Knife Competition at IWA 2019



This year at IWA, Tactical Reviews is throwing down the gauntlet and asking the knife trade “How sharp can you go?”. OK, it’s actually a lot less formal than that, a ‘just for fun’ competition to see who can create the finest edge on a knife blade, by any means they choose.
[Image: PT50A-grey-P1310517.jpg]
Entry is free and open to all exhibitors and visitors to IWA 2019 (see rules below). There is no prize beyond the warm feeling the winner will have, knowing they had the ‘Sharpest Knife at IWA’.
Come and find me with the awesome people at Chris Reeve Knives in hall 5, stand 5-135, on Sunday 10th March between 16:00 and 17:00. Get in early or you might miss out.
[Image: CRK-logo.jpg]
How is the sharpness measured? Using a PT50A BESS Certified sharpness tester:
The BESS ‘C’ scale of sharpness, developed by Mike Brubacher (Brubacher Edge Sharpness Scale) will be used to determine how sharp each knife edge is. The ‘Edge on Up’ PT50A tester uses a certified test media fibre and records the force required to cut it. The lower the score the better. As an example, a typical Morakniv factory edge scores around 250. See this guide:

A chart showing where on the BESS scale a blade is.



Every knife tested will be given an official sharpness score and certificate. A measurement will be taken initially in the centre of the blade, then the heel, then the tip, and an average value taken. This will test the sharpness over the entire blade, not just the easiest part to sharpen.

‘The Sharpest Knife’ Competition – IWA 2019
Rules:
  1. Open to all knives, custom-made or production. – No Razors allowed.
  2. Kitchen knives, though allowed, are NOT eligible to be overall winner; they have been found to have too much of an advantage, so may be entered for an honourable mention only.
  3. Any knife deemed not to be in the spirit of the ‘sharpest knife’ contest will be disallowed (surgical/laboratory etc.).
  4. Open to anyone – Professional / Maker / Amateur / User.
  5. Knives must be submitted either folded or sheathed, with the cutting edge covered.
  6. Each knife will initially have a single measurement taken. If the result is within 50 BESS of the leading entry, further measurements may be taken (at the discretion of the tester).
  7. Subject to the previous rule, each qualifying knife will then have a set of three measurements taken along the blade (centre, heel and tip) with the average BESS score counting as the result.
  8. In the case of a draw, the lowest individual score will be used for secondary ranking. If there is still a draw, the first one tested will win.
  9. The tester’s results are final – No knife may be entered twice.
The winner will be announced at close of the competition.
IMPORTANT: You undertake the competition at your own risk and your health and safety is your own responsibility. By taking part in this competition, you agree to indemnify the organisers and their agents against all costs, losses, damages, injuries, expenses and liabilities suffered as a result of your participation. No liability can be accepted for damage to any knife entered.

Mr. Sharpco,  In your post, Second toothy edge,
http://bessex.com/forum/showthread.php?t...09#pid4509

you did a most excellent job with microscope lighting.  Your images show great detail with reflection almost completely controlled.

If you would be so kind, what was your lighting method?  Directional and diffused?  Some combination with top scope lighting?

Great job with those images!

  Second toothy edge
Posted by: SHARPCO - 02-05-2019, 06:28 PM - Forum: All About Edges - Replies (4)

This is my second toothy edge. 


   
120 grit Norton Blaze

   
3M Scotch Brite belt Medium - 1 pass each side
and 
3M Scotch Brite belt very fine - 3 pass each side

   
Clean leather belt - 5 pass each side

   
Draw the edge through a wood block - 15 times




I think that if I make a toothy edge with a belt grinder, the blade must be wear out quickly.(My belt grinder Viel S5 is faster than Kally.) So I'll make toothy edge with 140 grit Atoma next time.

  The coarstest belt for sharpening
Posted by: SHARPCO - 02-03-2019, 07:53 PM - Forum: All About Edges - Replies (6)

The first belt I use when sharpening is blaze(plus) 80 grit. Sometimes I use blaze 60 grit. 

It's because, when I have to repair wide bevel(e.g. japanese sushi knife, meat slicer blade, zero convex edge, scandi edge), it takes very long time. I always use slack belt and the direction is edge trailing.

Then I switch it to 120 grit before it makes burr. Do you think is 60~80 grit is too coarse for sharpening?

What is your the coarstest belt for sharpening?

I got out my new 60x kingmas viewer and looked at my Excel razor...both a used one and a new one......I wish i could post images for you all to see!

This lead me to a 30 min journey on the internet to find that people actually STROP their used blades......someone built a handsome denim box.....someone uses green compound on a peice of plastic.....and a company in the UK makes a silicone pad and some magic sauce to sell as a Razor strop to save you hundreds of dollars per year!

Here is the link:

https://www.razorpit.com/


Has anyone on here that lives for a sharp blade done an investigation?

Can you really do much more than clean out the crud?

Have you done it yourself??......What really works well?

I go thru alot of blades, so this sort of thing appeals to me.

I would also like to dissect a blade, and test it but doubt I could pull it off as those little blades are so delicate.

I was shopping Amazon for 1x42 belts yesterday, when I came across an abrasive company I haven't even heard of. Reminds me of Klingspoor, in that they make their own belts.

Seems like they have practically anything a guy could ask for. If they don't have what you you're looking for in stock, they'll make it and still get it to you within a couple days... for Free. They actually seem to be teaming up with Amazon, and you can open an account with your Amazon credentials, and use your Amazon credit cards.

Please Take Heed:   
When you follow this link, there will be a "15% off your first order" pop up offer. Write that promo code down, put it on your clipboard, whatever. I just copied it and lost it by the time I needed it.

Red Label Abrasives

I ordered some of their ceramic belts, some Deerfos ceramic and other SC 1x42 belts suggested by our friend, Mr Sharpco. Smile

Hi Guys.....
 
My PT50B arrived yesterday......and my Kingmas 60x scope just came now!

Thank you all for the great suggestions.....Im having fun sharpening and looking!


I am looking for some input though.......Razor edge paper wheels.....I found a distributor here in Canada, so 2 10" wheels next....slotted ones correct??

What about diamond compound? see lots of stuff in syringes....but Mr. KG's video shows a paste in a small tub......and how do you load a virgin wheel?

I am going from the standard SG-250 Tormek wheel, to the paper.....so recommendations on the grit size too would be most welcome based on your experiences.

Thank you , Thank you!

Sam
