B66-721 SLIDING T-BEVEL. The Boss. Uncommon bevel with a sliding detent locking pin to fix the blade at different angles, patented 8/26/84 by Wilber Hill of North Manchester, CT, and manufactured and sold by the Hill Bevel Co. as the "Boss Flush T-Bevel." 9-1/2" blade, 6-1/4" japanned steel handle with BOSS cast into one side and the patent date on the other. There are five present angles; the sliding detent is designed to hold the blade in one of them while it is locked, and works smoothly. Near mint, the nicest example of this rare bevel we've seen. From the collection of Steve Dice. Fine 200-400
