Accurately cutting balsa strip

Cutting balsa sheet by hand using a metal ruler and a sharp modelling knife has always proven to be tricky to get the perfect cut of balsa strip.  One of the presents I received at Christmas was this simple and yet very effective balsa stripper.  The width of the cut can be easily and accurately adjusted by turning the dial.  The knife blade can be adjusted to the required depth and cutting angle to get the perfect cut.

Not bad for under £10 for the cutter including postage. I wonder why I never got around to acquiring one earlier..
