Also known as Crooks, Pointer Grind, or the K-grind after the man to whom the trick is most commonly accredited, Eric Koston. It is like a nosegrind, but the tail of the board is angled away from the rail/ledge on which the trick is performed, causing the edge of the deck's nose to also rub. Invented by Dan Peterka. thumb|300px|right
1-Approach the rail or what ever straight on this helps to get on it
3-Ollie on to it and put pressure on to the nose while turning the tail a bit.
3-when ready to get of just pop the nose a bit or ride to the end thumb|300px|left
