Here we have combination pliers. Now combination pliers are called so because on one end, we have a plastic or nylon cover and on the other end, we usually have metal. These also come with nylon on both ends for frame manipulation, usually on plastic or zyl frames without scratching them, but in this case, I like to use this tool specifically to increase or decrease the angle at which the front of your frame and the temple actually bend to accommodate the different size and shapes of patients faces. We always want to put the plastic or covered side on the outside of the frame, so that we're not scratching up the outside facing portion of the frame. And you'll notice with the tapered end, it sits and cradles right in that angle there and now we can increase or decrease as necessary in order to get the right angle.
