This guide details the expert process of fabricating a mainspring for an 1812 Springfield Musket, as demonstrated by master gunsmith Mark Novak. It covers analyzing original springs, designing new geometry, shaping and welding spring steel, and critical heat treatment processes including hardening via quenching and tempering in a lead pot to achieve the correct tension and durability. The guide emphasizes avoiding stress risers and ensuring proper material properties through precise temperature control.

This video demonstrates the intricate process of fabricating new leaf springs for British side-by-side shotguns when original parts are unavailable. Gunsmith Jack Rowe, guided by Larry Potterfield, details heating, bending, shaping, hardening, and tempering spring steel to create functional replacement springs for components like top levers, hammers, and sears. The process emphasizes precision filing and heat treatment to achieve the correct tension and durability.

This video details the complex process of fabricating a new mainspring for a vintage Marlin Ballard No. 2 Sporting Rifle. It covers diagnosing misfires caused by a weak spring, disassembling the breech block, and precisely shaping new spring stock from annealed steel. The process includes critical heat treatment steps of hardening and tempering to achieve the correct spring properties and a blue finish, along with safety repairs like deepening the half-cock notch and muzzle recrowning.

Master Gunsmith Jack Rowe demonstrates the process of making a replacement lever spring for shotguns. He details the identification of three distinct spring types (Greener, Scott, Continental) and provides a step-by-step guide for fabricating a new spring from 3/32 flat spring steel. The process involves careful marking, heating, bending, and refining the steel using common gunsmithing tools, emphasizing precision for proper function.

The Buck Hoodlum is a lightweight (15 oz) 10-inch survival knife praised for its versatility and value. It excels at batoning and splitting wood due to its full flat grind and wedge shape, and can be converted into a spear. The 5150 steel offers excellent heat treat and edge retention, even after heavy use.

The Glock 81 Survival Knife, made in Austria, features a 6.5-inch spring steel blade with a Rockwell hardness of 55 and a phosphate finish. Its polymer handle, similar to Glock pistol frames, includes a hollow compartment accessible via a removable end cap. The knife boasts a bayonet-style design with a bottle opener on the crossguard and comes with a sheath offering one-handed removal and MOLLE compatibility.

The Glock Field Knife 78 and Survival Knife 81 offer exceptional value for their low price point, leveraging Glock's signature polymer construction. While designed with a lineage tracing back to bayonets, prioritizing thrusting, their spring steel blades (HRC 55) are durable but require maintenance to prevent rust. The knives are not ideal choppers or slicers in their stock form due to a narrow profile and lack of blade belly, but can be improved with edge reprofiling.
