Grab custom sidebar in a page template

Hello,

I’d like to grab a custom sidebar I created and use it in a page template. Right now I’m using <?php get_sidebar(); ?> and that grabs my default sidebar. But I have a custom one named ‘blog’ that I’d like to use instead. How do I grab it? I tried <?php get_sidebar('blog'); ?> but that doesn’t work.
