Working with photoetch can be very fiddly but it's a great way to enhance your scale models. The Small Shop's Hold & Fold range of specialist tools can be purchased from Historex Agents - http://www.historexagents.com/yt.
They make using & bending photoetched brass detail sets much, much easier. Here we use two - the "Bug" & the 5.5inch Hold & Fold. Take a look.
