Curved edge kamisori sharpening

I have sharpened straight blade kamisori and straight razors a lot but i have had a few times to sharpen curved blade razors.
Normally I use one hand to sharpen razor blade but this curved one was not able to sharpen one hand accurately.
I found that to put on the other hand on the point is to make it stable to sharpen easily
However we should put on the fingers on the point gently
