Trust the toolman. Those Knipex pliers are the **** but the price is not for the faint of heart. The 20 inches fetch around $50. Made in Germany and self gripping.
I have a 12 in pair and a 16 inch pair, I paid 6o and 8o each for them off the truck. You find them for 50 let me know, they are by far the best addition I've made to my tool box
