I bought one of these after a recommendation by Rob Pulham. I was looking for something that would effectively score / cut brass sheet for scratch building my own items for a departmental coach conversion build. It arrived the other day so I'll post up a couple of pictures of it and probably make reference to it when in use to give my opinion on it. It's also what I recognise as a scrawker, a tool used by tilers to mark up tiles for cutting amongst other things. Cheers Toto
It was only after looking at your photo that I realised that the larger of mine (just like yours) has spare blades in a compartment in the handle - you learn something new everyday
