- Here is a sharpening session on a San mai blade with C130 core (1.3% of carbon).
Stones used are japanese naturals : Natsuya, Mikawa nagura, Ohira suita.
Edge is finished on leather strop with no compound.
Was that Bucker T and the MG’s, great knife sharpening with the natural stones.
Thank you ! Music is Maceo Parker band!
What sort of edge you get? I find the amakusa gives quite a toothy edge. I was thinking of getting a medium and fine morihei Hi stones because my amakusa is morihei as well. Cheers
Hey,
Amakusa is a natural stone about 800 grit. Morihei Hi are synthetic stones and you can choose the grit you want.
On this video I work from Natsuya to a fine Ohira, then leather strop. The edge I get is very smooth with some teeth but far cleaner than an edge from an amakusa
@@milangraviercoutelier6162 thanks for the advice!
I see you sharpen on the left side at about 30° angle or more compaired to right side.
Are you doing the 70/30 ratio and for longer edge retention sacrificing sharpness for thickness or what ?
it's a 1.5 years old video so I can't really remember. But I don't think you can really guess the angles I am putting from the point of view of the camera. I would say I was giving about 15 degrees angles both sides, but really can't say much about the sharpener I was 1.5 years ago. If I am doing little asymetric sharpening, I would do about 60/40, 60 would be the right side of the knife, meaning the one with no logo
A couple of years have gone by. I am sure much knowledge has been gained. Any changes to your sharpening technique that have been game changers for you?
Indeed, a new video would be nice as I changes some few things : 3 things maybe : I use Naniwa pro 3k , Yellow Coticule and a nature leather. I start at the heel and go gently at the tip but I don't go back to heel then. I would stop and start again at the heel if necessary, this give a lot of stability. Last one is edge leading strokes, I was mostly afraid of doing anything wrong but edge leading stokes with low pressure will deburr any foil edge and give much more durability to it.
@@milangraviercoutelier6162you use 3k naniwa in between natsuya and nagura or replace nagura with the 3k? Like natsuya > 3k > nagura > suita or natsuya > 3k > suita ?
@@yunghonyakihey. For the knives I make, they are thin on stones and they don't need more than a 3k to create a burr in few seconds. So I start with 3k to set my bevel. Then I use coticule that is like nagura grit maybe. Then I strop on leather.
I don't use Natsuya anymore for sharpening. If I need coarser I will use naniwa pro 1k or nsk diamond 800. Sometimes I will use mikawa nagura, it is burnishing more than coticule. If I want finer than coticule edge, I will do 3k naniwa pro, mikawa nagura, suita, leather
@@milangraviercoutelier6162 oh okay I understand now, thanks!
Have any experience with Binsui? If so, how do you feel it compares to that Natsuya.
Sorry no, I don't have Binsui. I got a red amakusa and it's coarser than Natsuya. Natsuya feel more dense, consistent, abrasive, better quality overall
wow, pretty stones, i might give one a try. There seems to be a significantly better selections of J-nats than American stones
What’s the last stone? Or strop leather?
Hello, last stone is Ohira suita and then I finally use a strop leather indeed. Made it myselft : walnut as base, the leather is "pikara" : cow leather, neck part. I use it without compound, works just great like that
@@milangraviercoutelier6162 Thank you for your kindly reply Milan. Please keep going to make a great works.
very nice, I am getting sick of American stones, they see to be shrouded in some type of mystery, the mines close down, and some items are no longer available (that is crap). all are 'rare' or 'vintage'. (that is crap also) Many thanks for the video.
wow thats a horrible taste in music. Nice stones
Thank you Jarrod!
