Humphrey’s Tool of the Week returns for 2013! He’s freshly groomed and excited about introducing you to a new range of tools this year. Today’s tool suggestion comes from Sam Mertens who was eager to show off his collection of pin vices. Sam used to work in some secret government laboratory before converting to jewellery and he saved this box of tools from a life of drudgery and now they are used in a creative capacity! So, a pin vice is used to hold onto something that is difficult to hold on to. You put the thing in the chuck and tighten the grip using the screw. Simple!
