Wedge Style Knife Block
The wedge style knife block is the old style quick-change block and is held to the vise in the same manner as the universal block. The left-hand knife is mounted and adjusted the same as with the universal block. The right-hand knife is held to the block by two shoulder screws which pass through the two friction springs and washers from the front of the block. This assembly holds the knife tight against the block, but permits the two strong springs to force the knife against the wedge.
The wedge is operated by a small hand lever and is graduated from 5 to 12 points, inclusive. By pulling the lever up or down the wedge moves and the knife follows the wedge.
