Even after all these years this is still the best video explaining about nagura. Hands down! Just a friendly reminder Alex but we need you to finish your book! I have been waiting for a couple of years now! LoL! Hope you and your wife are doing good.
Stephen You are exactly correct. The slurry left from rubbing the nagura stone will begin to sharpen/hone the blade, while at the same time encourage the base stone to begin to release its own grit particles to takeover the shapening actions. Not all of the beginning slurry made with the nagura is from the nagura, some is what rubbed off from the base stone and with the water and the abrasive action more grit will be incorporated from the base stone into the slurry to perpetuate the slurry.
For cutting up stones I use an old but powerful belt driven tile saw from the 1950s with a pump driven cooling twin stream of water onto the blade. The belt reduces the RPMs down and I have mounted a diamond tile blade. Hope this helps, Alx
Without knowing what brand of diamond plate you are using there will be some variables. I use the Atoma products and the two #600 Atoma's that I use for raising a slurry were worn out and mellowed by shaping axe head blades and knives. The axe work did the trick for sure and I cherish these two worn out Atoma plates for use in raising a slurry and final stone lapping just before I polish my stones surface and edges with Tsushima nagura. I suggest the next best thing is using the #1200 Atoma. For heavy abrading like flattening dished stones under running water I use the #600, and I keep these as like new and aggressive as I can. Hope this helps, Alex
i was just wondering if you have a preferred method for 'mellowing' a diamond plate? some seem to go pretty quick, some just wanna stay aggressive, i have one that im trying to ease in, i have offered my mom a full kitchen draw work over and ran chisel backs over it and still ts aggressive as heck. i also use it for lapping lower grit stones. nothing seems to wanna dull this bad boy.
So if i'm using an 8k grit honing stone, I should use a softer Nagura stone like perhaps a 6k grit? How often do you need to make this slurry durring the honing?
I found an American nagura in some trail many years ago ☝️ Just basically a very smooth but hard and small stone. It can slurry every oilstone and whetstone I have ☝️ I use oil when making slurry with it. Very fine liquid powder for sharpening
This video is Gold!! I have been trying to find it for days. Thanks! So what kind of blade is in the hacksaw? Metal cutting blade or just plain wood cutting blade?
Please recommend a reasonable whetstone( low price) to sharpen my stainless steel Japanese knives, i am very confused! The knife has become too blunt to use.
king 800/4000 and a king 1000/6000. those where my first two stones and they did the job perfect! and of course stropping at the end with a leather strop.
so if nagura is the name of the samurai who popularized the use of these particular stones, than what was the stone originally named? i hear them being referred to by wear they wer mined but not the name of the stone its self, im aware that theirs about 5 diff naguras from mikawa alone. and they can look drastically different, could you possibly do a video diving into the rabbithole of how to build a set of nagura, and what to avoid it would be much appreciated!
