Austin Style H50. 1.5 inch hand engraved sterling silver buckle with Austin style engraving. If not, Ever wondered how fine firearm makers achieve their incredible metal engraving? Unlike jewelry and western buckle engraving, which feature only surface engraving and embellishment; the depth and quality of firearm engraving comes from the actual removal of sub-surface material. This scooping effect allows the remaining surface area to be detailed and modeled.
