Streamlight ProTac 1L-1AA Flashlight

The Wave+ uses 420HC stainless steel for all blades and tools — a high-carbon stainless that holds an edge better than standard 420 stainless while resisting corrosion. The needle-nose and regular pliers are wire-cutters with replaceable cutting inserts — when the cutting edges dull (which takes years), you replace the inserts rather than the whole tool. All tools lock open in both directions with a liner lock, preventing accidental closure. Leatherman backs the Wave with a 25-year warranty. Made in Portland, Oregon since 1983. Users on r/BuyItForLife report 15-25 year lifespans on their original Wave models.

The Buck 110 uses 420HC stainless steel hardened to 58-60 HRC — harder than most stainless knives, soft enough to sharpen on a basic whetstone, and hard enough to hold an edge through a full hunting season. The lock-back mechanism uses a rotating bolt that drops into a notch in the blade tang — one of the strongest locking designs for a folding knife. The nickel silver bolsters and genuine leather handle scales develop character with age. Buck has been making the 110 since 1964 in Post Falls, Idaho, and it's been the best-selling folding hunting knife in America ever since. The Forever Warranty covers workmanship and materials for the life of the knife.

The PM2 uses CPM S30V powder metallurgy blade steel — an alloy with a fine carbide structure that maintains a working edge 3-5x longer than standard stainless knife steel. The Compression Lock places the lock mechanism at the spine of the handle rather than the liner, creating a fundamentally stronger locking geometry that is also ambidextrous. The full-flat grind (from spine to edge) makes the PM2 an exceptional slicer — the blade thins toward the edge on both sides with no secondary grind. The G10 handle scales are bidirectionally textured and will not crack, absorb moisture, or degrade. Spyderco offers repair services and spare parts.
