Thanks Tim, as you know planes aren't my thing , do use some plastic card so might be ok for marking that . What about as a tool for foam board , don't want something too sharp but capable of of doing an imprint say for mortar lines , that sort of thing .Only if you do a fair bit of scratchbuilding or build planes John. I haven’t used either of mine (I have a Tamiya one for re-scribing panels, and a bigger one from Wikes I use for cutting thicker plastic sheet) for a long time.
