Sharpening/Polishing knives using micron paper

How to use a steel to straighted a knife blade and how to polish and maintain a sharp edge on your knives using micron abrasive paper.

To see the results of this knife in action, watch the "Roll your own Sushi Video" It cuts like a hot wire through butter.

interesting.. i normally use a whetstone and never sandpaper..... also i usually just push towards the blade not both towards and away from the blade... does all this apply with whetstones too or is it a different technique?

This micro abrasive paper.

As I understand the physics of sharpening, pull away for all strokes (causes the metal to "lip" over the future blade) and the final few strokes push blade into abrasion (removes "lip" and leaves sharp edge).

Thanks GoldenPizza. I'm in the process of polishing a Puma knife that has been seriously scratched by sharpening stones.

Unable to find chromium oxide or calcined aluminate so stuck with sandpaper up to

3000 grit then metal polish until all sanding marks gone. (100-200 applications btw.....)

4000 grit is available but $75 a box keeps me from getting any.

Can you tell me where to buy the micron paper please? Thanks a lot.

google micron abrasive paper. there is a woodworking place in NY that carries it.

Got 7micron and 0.7micron lapping paper at Lee Valley Tools in Halifax NS Canada. This is now what I use on my Shun Kaji 6" Chef's knife. This knife has SG2 Powder steel so I can sharpen it razor sharp with great consistency. I find this better than stones because the plate glass never becomes curved and even my 8000 ceramic stone cant polish this fine. This video inspired me and changed my sharpening technique to perfection. Thank you!!!!!

@pirinst eBay has loads of suppliers for cheap.

I got lapping paper at Lee Valley Tools in Halifax Nova-Scotia. 5 Micron and 0.5 Micron and the results are amazing on my Shun Kaji chef knife. I appreciate your video but i think you need to perfect your stroke technique.

Nice job Bro... Well done!

use a block to elevated the paper. make sure the surface is flat. the best flat surface is plate glass.

the reason 40 micron feels rougher than1000 grit is because it is rougher, approx. 635 grit. since grit is a number of abrasives per linear inch, in order to figure outgrit from microns, you take 25,400 (number of microns per inch) and divide by X, where X is the size in microns of the paper you are using (i.e. 5 micron, 1 micron, .3 micron, etc.)

how would you sharpen a knife like a whustof (who have a gard) and it would be hard to do it on a flat surface. could you explain? thanks

Hi there. I recently acquired a Katana and it has never been sharpened finely. I have used a grit stone to make the edge sharp, however in the process I have scratched the side of the blade severely. Would Micron Paper be able to work out the scratches for a fine finish? Note: the scratches aren't deep, but the blade has lost its glossiness. Thank you and I look forward to your answer.

8:08 not sharp? vegetable tests are much better (esp. tomatoes)
