I saw this block plane on eBay.co.uk – just too late to grab it! A much smaller version of the other two aluminum block planes made by “The Boston” company in my collection. This one is 6¾” in length, with two unique features. The first is a finger “tab” in the toe of the plane, replacing what would normally be a small circular finger depression. The second is that whilst the blade is held in position by a fitted lever cap and cross-brace, pressure is provided from under the blade by means of a machine-bolt. As the bolt is screwed in, it forces the blade-assembly up against the cross-brace, holding it rigid.
