Good question. Many years past I bought a Strider SMS, I think was the model. It used, I believe, s60v steel not the s30v. When I emailed him he advised the knife, including the blade, was guaranteed for life. Hands down no Bullshit. To bad I lost the thing making an arrest in a field. A fight issued and it must of slipped out of my vest trauma plate pocket. I didn't realize it was gone, de-weaponing (not sure that's a word) at the county jail. Anyways Strider seemed damn sure of his products. For what it's worth....
