Unusual Tools: David Trimming Plane

Picked up this lovely little trimming plane yesterday.  The base is only 8 cm long.  It uses razor blades and gives you three positions to insert them:  on the front, in the middle (as a skew) and on the back (on a curve).  

Made by a Dutch company named "David."  It's the first tool made in Holland that I've every encountered over here.  I love their trademark!  Obviously a biblical reference intended to suggest that, although they're small, they can knock down the bigger guys.  Along with slinging a stone, the figure also looks like it's flipping the bird, although this is probably not intentional.
