The Cheerio Razor Blade by the Wafer Razor Co. Ltd. of Sheffield. Individually wrapped war department 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 utilized by MI9 including 'Fleet', 'Dawn' and 'Cheerio'. Some minor rust staining to the blade. Still retains a little magnetism and will 'disrupt' another compass if held close. We have four available, priced individually. Stock code E22537+.
