Hey guys. I own a Takeda 240 iron clad gyuto.
When i received about 6 months ago there was a very pronounced shoulder.
After using it a couple times I decided it was time to remove it.
I read all I could, and saw what magnus had gone through, and saw that this was actually a very common problem.
SO, I used some from my experience from sharpening razors for sharpening my Takeda.
Instead of using the bevel and trying to freehand the shoulder away, usually this causes a lot of the kurouchi finish, that is desired anyways.
1. I simply applied 4 layers of electrical tape on the spine.
2. I then laid the knife completely flat on the stone, just to make sure, just the tape and the pronounced shoulder were touching the stone.
3.Then japanese style grid away on a 4k Naniwa lobster stone for about 100 strokes every section, and 30 italian style grinding.
4.Noticed it was a little higher then what i wanted so I went to 7 layers, this was to target the sharpest ridge of the shoulder more accurately.
5. used the knife for a few days
6. touched up with 8 layers of tape to make the tip a real laser, and to thin it out a little more at the top of the primary bevel.
*note: this shoulder grinding does not affect the primary bevel in any negative way, only the shoulder is effected.
*note: I consider japanese grinding to be back and fourth on the same spot (samurai style) and italian griding to be the whole knife sharpened with one stroke.
*note: I only worked with the 4k stone because i was worried about ruining the finish, and did not want to over do the removal of the shoulder trying to keep it at a level i would like.
*note: the number of layers of tape will be different for the sasanoha, but should work fine for 210-240-270+ gyutos
Since i did it many months ago I don't have images of the before. and Admittedly i had to revisit this method again because i wanted more thinning in certain areas.

This has made me love the Takeda, as it has some what my own flare to the grind.
let me know your thoughts.
