Martelli! WOWZER! I have at least 8 mats and a couple of rotating ones as well. I have duplicates in my little fishing shack on the sound and back in the city as well. My latest purchase was the Martelli. I swear it seems to sharpen my rotary blade with every cut! The difference is amazing. I use the Martelli cutters and blades as well. They are all pricey but I got on their email and picked up on their sales. Great discount! This is the sweetest cutting I have ever done. Then my kids bought me the rotating Martelli for my birthday. I am in love with my kids! And my Martelli mats!
