Complete Hardware Installation Process for Shebag Lizard Skin Handbags (Special Standards for Crack and Scale Shedding Prevention Exclusive to Lizard Leather)

Lizard skin features thin texture and brittle scales that tend to curl and crack under force. The core principle of the full set of hardware installation lies in multi-layer reinforcement, precise pressure control, pre-fixing cushioning and low-stress fastening. Shebag adopts custom hand-fitted molds combined with inner lining composite reinforcement, and the whole workflow consists of five standard procedures including hardware material preparation, pre-installation treatment, three mainstream fastening techniques, final locking finishing and quality inspection.

All hardware components are crafted from precision cast 316 brass with multi-layer vacuum electroplating. The stud posts are treated with rounded chamfers without sharp edges to prevent piercing and tearing the scales. Special reinforcing layers are mandatory for lizard skin while omitted for ordinary cowhide. The surface cushion layer adopts 0.3mm ultra-thin lambskin lining in matching hues, which closely adheres to the leather surface to disperse hardware pressure and stop scales from whitening and curling at edges. The middle load-bearing layer is made of 1.0mm imported shaped vegetable-tanned leather backing, serving as the core for stress diffusion and fully covering all force-bearing hardware positions. The inner isolation layer is 0.25mm microfiber thin lining that isolates metal friction between the back of hardware and bag lining. Supporting fastening accessories include soft yellow glue that will not damage the finish of lizard leather, special thread anaerobic glue for anti-loosening of screw fittings, widened pure copper gaskets and custom concave-convex molds sized to match hardware diameters to avoid direct compression on electroplated hardware surfaces.

Pre-installation pretreatment covers leather protection procedures exclusive to lizard skin. Fine silver scribers are used to lightly mark positioning points; oil pens and sharp carving knives are forbidden to avoid permanent stains penetrating the leather. Symmetrical hardware pieces are aligned and calibrated on both sides with a positioning error no more than 0.15 millimeters. Precise layered punching acts as a critical anti-cracking step, and the leather is not punched through in one single operation. For the outer lizard skin layer, punches with the same diameter as stud posts are applied for vertical gentle punching, and the edges of holes are slightly chamfered by an edge sander to smooth cut scale edges. The reinforcing vegetable-tanned backing and microfiber lining are expanded by 0.2 millimeters synchronously to reserve tiny buffer gaps and prevent pulling of lizard skin during compression. Oversized punches are strictly prohibited, as loose holes will cause hardware wobble and long-term stress cracking of scales. After punching, soft yellow glue is thinly brushed on the bonding surfaces between reinforcing backings and lizard skin, and the materials are left to stand at low temperature for 15 minutes for semi-dry adhesion. Traceless double-sided positioning adhesive is applied to the inner layer to temporarily fix hardware, eliminating displacement and scratches on scales during riveting or screw locking.

Shebag applies three mainstream hardware installation techniques according to different usage scenarios. The first technique uses double-layer male and female rivets, the most widely adopted solution for hand strap lugs, chain rings and load-bearing hardware on bag bodies. These double-sided rivets feature flat metal surfaces on both sides and deliver maximum tensile strength, ideal for high-load positions on lizard leather. The assembly order from exterior to interior goes as hardware head on lizard skin, lizard leather, lambskin cushion lining, vegetable-tanned reinforcing backing, microfiber inner lining, widened copper gasket and rivet post tail. During fastening, a vegetable-tanned leather cushion pad is placed under front hardware, and custom concave molds fit hardware caps to protect electroplating from scratches. A thick rubber buffer layer pads the bottom anvil, and manual light hammering is implemented for riveting in multiple strokes; one-time heavy striking is banned as intense force will directly crush lizard scales. Rivet posts are evenly flared to wrap copper gaskets, leaving smooth backs free of sharp burrs. This method delivers tight mechanical engagement free of loosening, and multi-layer backings disperse tensile force to avoid leather indentation and scale shedding after long-term carrying.

The second technique relies on Chicago screws or hidden screw locking for clasps, flip locks and detachable shoulder strap buckles. This detachable serviceable structure stands as the primary craft for high-end Shebag lizard leather bags. Each hardware piece comes with a decorative cap on the front and threaded posts on the back for internal screw fastening. For lizard leather protection, complete circular vegetable-tanned backings are pre-glued inside holes so screws never press directly onto lizard skin. A tiny drop of anaerobic anti-loosening glue is applied to screw threads to eradicate rattling and loosening after prolonged use. The installation sequence involves threading hardware through composite leather materials, fitting thickened gaskets on the reverse side, and evenly tightening screws with a manual torque screwdriver under controlled torque without over-tightening. Excessive tightening squeezes leather and creates permanent indentations and curled scales. A major advantage of this process is that oxidized or damaged hardware can be detached and replaced without damaging the original lizard leather.

The third technique adopts light compression with hidden snap buttons and bottom feet, suitable for low-stress decorative hardware including bag base feet and magnetic snaps. These slim small hardware pieces require minimum compression force to stop partial scale crushing. For base foot installation, four layers of composite reinforcement are applied at the bag bottom, consisting of lizard skin, double vegetable-tanned backings and inner lining, paired with wide-base feet to expand contact areas and prevent leather damage under ground contact pressure. Upper and lower molds for snap buttons are precisely matched with fully soft leather wrapped mold contact surfaces. The press machine performs low-pressure compression in multiple cycles with each compression cycle shortened by 30% to avoid whitened finishes and cracked scales on lizard leather. The base of magnetic locks is entirely wrapped with vegetable-tanned backing to separate metal from direct contact with lizard skin and eliminate leather deformation caused by magnetic pulling force.

Advanced cross-reinforced fastening is designed for large heavy hardware such as lock heads and thick chain lugs. Pure rivets or screws still carry tearing risks under long-term heavy loads, so Shebag implements dual reinforcement combining rivets and hand saddle stitching. Hand saddle stitches with a spacing of 0.8 millimeters are pre-sewn around hardware bases, with stitching concealed between layers of reinforcing backings so no pinholes are visible on the front lizard leather surface. Threads only penetrate inner reinforcing leather without piercing outer lizard skin, completely avoiding scale structural damage from pinholes. Stitch endings are hidden inside lining interlayers with internal locked knots, leaving no exposed loose threads that rub against hardware and create scratches.
