When it comes to knives, you can do a lot better than whatever you relied on in your younger days. Yes it's full of memories, but it's more useful as a paperweight than a knife. For a time-tested blade with serious details, check out the Twitch II from the knife makers at SOG.
The Twitch II is based on a classic lock back design and features the brand's assisted open technology. That makes it extremely easy to open, while the lock makes sure it stays closed when you need it to. The full metal construction is sturdy and durable, complemented by a beautiful rosewood handle, and includes a pocket clip that keeps the thing secure in your daily carry.
