Hi Gustas, I own a Switchblade. You are correct that holes are drilled through the base of the snowboard to mount the Switchblade. You must counter sinc the holes so that the screw heads are flush with the bottom of the board. There are people who are very knowledgeable about how to sharpend ice skate blades. I'm not one of them. But, the blade is grooved along the edge as opposed to being a flat edge that is sharp on the corners. Hence, a tool is provided with the Switchblade (top of your picture) to sharpen the blade. The angle bracket is about 30 cm long and is approximately 90 degrees. I have not measured the ange, but it is pretty close to 90 degrees.
