Surprised even tubeless would stand up to that. I wouldn't like to fall on that .
Oh, it sucks just as much as you might imagine. Even getting scraped by one as you ride a trail can cause damage. My G-form knee pad got a hella rip in the fabric from one of these things (not to mention the hella rip it left in me!). Fortunately, the partner had stretchy fabric that made for a perfect patch.
