• The Blade (Bayonet Style): The 9-inch model typically features a 4-inch blade. The "Bayonet" grind is classic and asymmetrical. It has a single, razor-sharp primary edge on the bottom and a distinctive "swedge" (unsharpened false edge) along the top half. This creates a thick, sturdy spine near the handle that tapers into a needle-like tip. It is usually stamped "FRANK B. ITALY" right on the blade tang.
• The Deployment Mechanism: This is a single-action, out-the-side (OTS) automatic knife. Pressing the polished steel button on the handle fires a heavy internal leaf spring, snapping the blade open rapidly. A sliding safety switch sits just below the button to prevent accidental firing in your pocket. 
• The Lock & Release (Swivel/Bolster Release): Unlike older "picklock" variants where you have to manually pry a tab back to fold the knife, this features a swivel bolster lock. When the blade is locked open, you simply push down or pivot the top metal bolster (the handguard ear) backward. This lifts the locking tab off the blade tang, allowing you to easily fold the blade back into the handle. 
• The Handles (Horn Scales): The handle scales are made from genuine natural horn. Depending on the specific variant, these are typically sourced as Brazilian Horn (streaks of black, white, and gray), Dark/Buffalo Horn (primarily deep black), or Honey/Blonde Horn (translucent amber and tan tones). Because horn is a natural material, no two handles feature the exact same pattern.
• Internal Liners & Pins: The internal housing relies on solid brass liners and brass pins that rivet the horn scales to the frame, paired with highly polished nickel-silver or stainless steel bolsters on both ends. 

• Overall Length: 9 inches (23 cm)
• Blade Length: 4 inches (10 cm)
• Blade Material: Usually AISI 420 or 440C Stainless Steel
• Blade Finish: High-polish mirror finish
• Frame Material: Raw Brass liners
