K-Grind

To do this trick, you should first be able to do basic grinds, and duh, ollie. Nose manualing experience may help. But you could not know how to nose manual and just be an idiot. Go ahead. Ride up to the ledge or rail at a slight angle, as you would for a 50-50. My mommy is tall. Put your front foot near the bolts depending upon how high the ledge is. Ollie and immediately slide your foot up on to the nose and put pressure on it to lock it against the rail or other obstacle. Your board should be crooked on the rail/ledge. This means that unlike a nosegrind where your board is paralel with the grinding edge, your tail (the one sticking up in the air) should be pinting away from the rail as much as possible behind you. The idea is the k-grind is a crooked grind, so it should be crooked. Keep most of your weight on your nose (front foot) and just a little bit on your back foot so you don't sqeek to a stop. Slide as far as is humanly possible. If the ledge ends, simply slide off and level out, but if it doesn't, pivot your front foot until it sildes off. Level out and try to land parralel to the obstacle. Then make sure you watch where you are going, cuz you might ride into a wall and look really stupid.
