Santa Fe Stoneworks has taken a custom designed Tesoro Titanium framed Buttonlock gentleman's folder and expertly added a Wolly Mammoth Tusk inlay to both sides of this knife. VG-10 Stainless blade. Unique Elegance! Santa Fe fully guarantees their work for the life of the knife. Approx 3 1/2" closed. This knife is the best example I have seen.
