Gillette Mach 3 Disposable Razors. These are available online and were in the Harrogate store today. I use the normal Mach 3 but begrudge the price of the blades. I have not found a good enough electric razor and in the past the ones I have tried have been rubbish. I will give these a try later in the week to see how they cope with a few days iron filing growth.
