Here I was, thinking that I'd managed to get through all of Friday and Saturday without buying a single thing.
Then I remembered that I had, in fact, bought three things.
My travel pass for the month of March.
Two copies of Knife Repair and Restoration.
I stumbled upon this book an a Norwegian site, then looked for a second hand copy on Abe Books. €35 to €96! Plus €35 in shipping!
I bought new, including extortionate DHL shipping charges, it came to about €29.
