This isn't just any penknife, this penknife has been with me since I was an Art student in the latter part of the last century. I have painted it with it's most important tool exposed, the corkscrew. Other tools include a natty little pair of scissors, a phillips screwdriver, a flat screwdriver with bottle opener thingy. I use it these days to open tins of paint and to sharpen pencils, oh and open bottles of wine! Oil on gesso 16cm x 12cm.
