So, there's a HUGE misunderstanding about freehand knife sharpening.
You DON'T have to spend hours.
I'd say, if you are spending more than 15 minutes per knife, you are doing something wrong.
Most common mistake is using the wrong grit# stone.
If you don't see any progress after 5 minutes, then, you are using the wrong stone, most probably.
This video is just for demonstrating that you don't have to spend hours and hours for freehand sharpening.
So I didn't explain about in details, where to place fingers, how much pressure to apply, etc, etc. (Deliberately omitted.)
In the next video, I'll talk about the stones.
What I have tried, what I use now, what I don't use now, and ... where to put money...
