K...

I used to be able to do these very consistently and more technical years ago. They have since fallen into the section of forgotten tricks.

I managed a number of them including this one and a couple of back to back. Not the 3 back to back I like to sign of on bit they are slowly coming back.

It is called a K grind. I think the K stands for Koston (Eric) who may have invented them. It's a combination of noseslide and nose grind.
