Vintage Mother-of-Pearl Folding Pocket Knife with Fraternity or Masonic Inlay

This is a vintage multi-blade folding pocket knife, likely a pen knife or tuxedo-style gentleman's knife. The handle scales are crafted from genuine iridescent mother-of-pearl (Nacre), displaying characteristic white, cream, and faint pastel overtones with a high-luster finish. Central to the scale is an ornate, three-tiered metallic shield inlay featuring blue enamel and potential Greek or fraternal lettering, suggesting it may be a membership or commemorative piece for an organization like the IOOF (Odd Fellows) or a similar fraternity. The knife features two visible pins securing the scales to the internal brass or steel liners. The metal bolster area is absent, featuring a clean 'slab-sided' construction common in early-to-mid 20th-century decorative cutlery. One partially visible blade shows signs of oxidation and surface wear, consistent with an estimated age from the 1920s to 1950s. The mother-of-pearl appears to have some minor edge chipping and surface scratches but remains intact without major cracks. Small visible gaps between the mother-of-pearl and the metal liners indicate natural shrinkage over time. No maker's mark is visible in the closed position, but such pieces were often produced by premium manufacturers like Case, Remington, or Sheffield makers for fraternal jewelry catalogs.
