We did our take on the classic Hewlett design. We rounded the edges and added a 5.5mm hole to accommodate rivets or cordage! It has a medium (600) surface on one side and a fine (1800) surface on the other. It's 3 1/2" long, 1" wide, and less than 1/16" thick (.055"). The plate and it's plastic sleeve weigh about 1 1/4 ounces. Made in the USA.
