No problem mate just nipped in the garage and looked at mine,were the matt's fold it has a machined fold which is a lot thinner,with a very sharp blade and something flat and even under it,i reckon youd get a very neat cut.
Just to note for anyone interested when folded they fit perfectly in a standard UK Army bergen,the rivets and velcro seal around the frame lift up and it neatly slides in and the seal will come back together with no difficulty at all,this make the bergen comfortable to wear and the matt wont take up any space in the main body.
Its the first thing i get out ,so that i can lay any gear out on to it keeping it clean and off the floor.
Also the current pound land tarps fit over one perfectly wrapped over it, set up for leaning against a tree on sitting on the floor then later you can lift the tarp off and the matt clean to go in your hammock/tent,sitting on one of these really stops the cold coming up into you
