The knife itself has a 3.5 inch Ti nitride coated blade, anodized handles, and a diamond sharpener which sharpens blades quickly and easily. One of the great things about this set is you can also use the sharpener on other knives. Lastly the knife comes with both a clip to hook the knife on to clothing and comes with a thumb stud for one handed opening.
