Heyo,
Was mounting some art yesterday at the space and have left the angled mount board cutter I bought in with the other sharp things, felt this was the best space for it as it goes with the cutting matts etc. in textiles best.
Not quite a bit enough purchase to count as a new tool but FYI!
Allows you to make angled cuts such as the one shown. Can be run easily along a metal rule using the groove on the tool. no risk.of slipping and cutting yourself either!
