It was me. I said don't use a pencil sharpener. Use a scalpel. It does become a problem at airports nowadays. At the check -In. I say but the blades are separate from the handle. At the X-Ray machine conveyor belt in my bare feet and belt-less trousers, braces optional, aftershave in a see through bag. I say but the blades are separate from the handle, it's the tool of my trade. Vital for my craft. So they say OK. And I board their craft for a flight for the other side of the world. Meanwhile tweezers are confiscated.
I do confess that I have grown accustomed to a little metal pencil sharpener that I purchased in a Warsaw art shop in February 2011. Must be my age.
