Peeling off from JP's thread about hammers MY 2ND FAVORITE HAMMER let's discuss planes. I have quite a few, but my favourite, which has not been supplanted by some (expensive) subsequent purchases is my Stanley 93 plane.
I can use it for finishing tenons (as intended), tidying up shoulders in general, trimming off the end of dowels; and without the nose, getting into corners. It fits my (7 1/2) hand perfectly.
