Probably colonial, likely American and recently turned up in California. 8 ½” diamond section blade with rounded base ahead of the elongated diamond section guard. Both features specifically Spanish. Swelled medial wood grip with iron ferrule chiseled with the owner’s initials and pommel cap. The wood skillfully carved to shape, not lathe turned, indicative of a rural, if not remote origin. Thumb rest notch carved to the grip confirming its use as a fighting knife. Untouched with wonderful age character. Wonderful colonial character and equally at home in a Spanish Southwest or Caribbean collection.
