The cut-resistant material blocks the chainsaw chain, thereby protecting against cuts from hand-held chainsaws. In the case of STRAUSS cut-resistant trousers of Type A, this applies up to a chain speed of 20 metres per second. From the hip downwards, a multi-layered layer of loosely woven, very long and fine, tear-resistant threads is incorporated into the front of the trousers; these wrap around the drive sprocket of the chainsaw as soon as it cuts through the outer fabric.
