<p>A tool block (200) has pockets (214) for receiving chisels (30) radiating from a pivot point (222) about which a lock (224) is pivoted. The lock comprises an arcuate fork (234) sliding against an arcuate edge face (216) of the block (200). The fork (234) engages the bolster of a chisel (30) preventing it being withdrawn unless the lock is pivoted to release the chisel. The block (200) incorporates a blade sharpener (90) comprising an abrasion plate (110) mounted for transverse movement in a slider (100) when the blade (36) of a chisel is inserted in a longitudinal direction.</p> |
