Based on the famous Stanley No. 1, a miniature bench plane, 140mm(5.1/2") long with a 30mm(1.3/16") x 3mm thick blade, fitted with a Lie-Nielsen improved chipbreaker. It is available with a cast manganese bronze body only. Size wise it is not dissimilar to a block plane. This may give a clue to its original intended use, as a small plane for trimming type jobs and final touches.
