First I would like to say Hi to everyone, I am new to the forum but a long time reader. I have just bought a "british SAS" wire saw from Birgade Quartermasters, and the first thing I did was test it out on the cardboard box that it came in. After cutting several inches in I noticed that the small wire that is woven around the larger three had broken in several spots. Is this normal, or was I sold a cheap knock-off?
