The Kleen Razor Blade by the W. R. Swann & Co. Ltd. of Sheffield. An individually wrapped WD broad arrow marked razor blade. This has been magnetized so that when suspended by a thread in a glass of water it would act as a compass for escape and evasion purposes. Various different brands were used including 'Fleet', 'Dawn' and 'Cheerio'.
Some rust staining to blade but still retains some magnestism and will 'disrupt' another compass if held close. The blade is also 1945 dated. One only. Stock code ENIV-EC.
