Bonded mouldings can add so much height to a windshield that a normal cold knife blade does not have enough clearance between the pull handle and the bend. These Long Shank Cold Knife Blades have an increased length that can provide you with up to 3/8" more room between the cutting edge and the cold knife pull handle. Made of stainless steel. They work on all cold knives and are especially useful on push-button release cold knives. Made in the USA.
