The Grid by Silicone Zone - http://www.siliconezone.com - is a square silicone trivet, pot-holder, and jar-opener which I got off the rack on a whim (and a gift certificate, heh heh). It was actually the jar-opener function that caught my attention because many a time I'd try to open mayonnaise jars, tea bottles, and the like I'd use my shirt or any rag lying around to cushion my hand. Sometimes that would work, but not all the time.

With Silicone Zone's The Grid, there's never an unopened jar or bottle in the house again! It's really effective, it makes opening stuff so easy. It looks so modern and decorative too, just love those vibrant colors!
