The blades are sharp, My daughter has been using the Ulu blade in the Mano housing to de-flesh a Buffalo hide a friend gave her. The Ulu blade has worked great. Have re-sharpened it once but its a large hide. She originally tried the Ulu in the Fillet Mano housing but prefers it in the Mano housing for the feel in her hand. Looking forward to trying the skinning blade but friend was in Wyoming when he skinned this one.
