That's a useful looking thing.
A question, you see the spare blades at the left of your picture. In the UK, the knife that they fit is generally referred to as a "Stanley Knife". Although the format is now used in a variety of different knives from dozens of manufacturers, we still call them Stanley knives. I'm not sure if Stanley came up with the design originally or not. I guess it's like people call vacuum cleaners "Hoovers".
Is that the same on your side of the Atlantic (or anywhere else people might read this) or is it just a UK thing?
