Louis Martin Custom Knives
Handmade Switchblade Knives
Quick Answer
A switchblade (automatic knife) opens its blade via a button or switch that releases a spring mechanism. Out-the-front (OTF) switchblades deploy the blade through the front of the handle. Louis Martin switchblades are crafted in Damascus and high-carbon steel with precision spring mechanisms.
Switchblade knives combine the convenience of instant one-hand deployment with the craftsmanship of handmade blade work. Louis Martin's automatic knives are built with precise spring mechanisms tuned for reliable, positive deployment every time.
Characteristics & Construction
Mechanism Types
Side-opening automatics (classic switchblade) and OTF (out-the-front) designs. Side-openers are simpler and more robust; OTF knives offer a unique deployment that is extremely popular with collectors.
Legal Notice
Switchblade carry is regulated by federal law and state statutes. Federal law prohibits interstate transport of switchblades; state laws vary on possession and carry. Verify your local laws before purchasing.
Care & Maintenance
- 1
Service the spring
Automatic mechanisms rely on precise spring tension. Have the spring inspected annually if the knife is carried daily.
- 2
Keep the channel clean (OTF)
OTF knives are prone to debris accumulation in the blade channel. Clean with compressed air regularly.
