Straight razor honing on Dan's surgical black arkansas stone

Straight razor heljestrand MK 4 - refreshed on jnat with tenjou and meirjo asano nagura.   After the razor was touched up, I came straight to this stone with oil.  I like the surface prepped with my Atoma 400 as it is easy to refresh the surface when needed.  I might lap the other side with sandpaper up to 600/1k at another time.  

So far this stone has given great edges. I would prefer it over most jnats (with the exception of the very nice/fine ones).  decent speed in my opinion and I usually finish in about 5- 7 minutes.  Wanted to enjoy the stone today though and make a video.  

Would recommend surgical black ark to anyone wanting a sharper edge or looking to get into naturals.  I prefer jnat edge, but can be very hard to find correct jnat.  I recommend 3 inch wide stone to avoid any mistakes during the finishing process.
