This knife features a blade on the side to open friction-fit backs easier and quicker. Just place the blade on the rear of the watch lugs with the blade under the edge of the case back. Give the knife a twist and the back should come off most of the time on the first try. In the rare occasion when this technique does not work, you can use the end of the blade.
Overall length is 5-3/4". Features a steel blade with a wood handle.
