unfortunately useless on a worktable.

As my old cutting mat has become unusable (for 10 years) I am looking around times on Amazon. I chose this one because I spoke to the color and size. However, I remembered the first time using just about any negative points on which may have a cutting mat. It is printed on both sides: once in cm and the other side in inch / inch. because both sides are very smooth, the thing often slip back and forth, what extremely interfere with the work. the mat is strong enough to prevent the penetration of the blades. Unfortunately, this material is not as good as my old mat which locked the flat interface. Instead, you have a collection at the interfaces, as you know it from plastic, and after an operation, the mat a scarred area of ​​unevenness. This makes it no longer useful for precise fine work unless one is looking for a place that has not yet aufgeritzt.
Meanwhile, I use it only as a storage area because the work it more annoying than helpful.
Who wants to set a cutting mat, you should get one of these silicone / jelly-like material. These last much longer and the interface fits flat again together as if it were brand new.

As my old cutting mat has no company logo, I do not even know where I can get it, or what I should order. If anyone knows what kind of mat I had, please leave me a comment. The store where I bought it then there is no more now and I'm looking desperately for a new mat :)
