The next generation nut key. The Nutbuster has a moulded rubber handle designed to protect your hands when bashing at stuck nuts or tugging at jammed cams. The rubber handle can be removed to reveal a 17mm spanner for tightening loose bolts. Made from the finest Sheffield stainless steel this precise tool will last you for years, unless you drop it, so tie it to a racking biner with some thin accessory cord.
