Thin and accurate, the tip of the Pro Key is precision ground for nut removal even in tiny slots; whilst at the opposite end there’s a wide, flat surface for a firm and painless push with the palm. Large holes along the length of the key keep weight to a minimum and a wire gate allows a direct clip to the harness. The Pro Key can also be bought with an optional, extendable leash and clip that means you’re safe from dropping it in tight spots.
