Shardblades sells a wide selection of Damascus steel knife blanks and blades. All of our Damasuc steel knife blanks have been heat treated and pre-sharpened. Please note that Damascus still is a high carbon steel blade and will rust if not well taken care of. Damascus steel should never be stored inside a leather sheath as the sheath contains moisture that can corrode the blade. Instead when storing keep the blade clean and then apply a thin layer of oil to preserve the blade in edge. The overall quality of these knife blanks are kept to a high standard. If for any reason you are unsatisfied with the blank that you have received please contact us and we will be more than happy to help you correct the issue.
