As a retirement gift, you should get him a pair of Ideal Stripmaster wire strippers (Klein also has a re-branded version too) - he could see what crappy strippers he's been using for his entire career. Stripmasters would have each of those wires stripped in half a second - no fuss no muss! You can find brand new ones online for about $40
Good video
