I was recently given this Blade by my grandfather, who brought it back from Mexico many moons ago. On the blade, both sides, it has a floral design and a Spanish inscription, which appears to read; "No Me Mires Por Que, Me Sucnas(e instead of c, maybe)". I don't speak a lick of Spanish nor have any idea what its made of. It appears to have a leather stacked handle with metal washers in between the leather washers. All I CAN comment about it is that this is my second day with Diamond Credit cards trying to hone an edge on it, so it seems to be extremely hard. Grandfather mentioned something about a truck spring...Any info would be appreciated.
