Since the introduction of its first folding knife in 1981, Golden, Colorado-based Spyderco has produced a steady stream of interesting and innovative EDC folders, flippers and fixed blades.
Heck, even that debutante, the C01 Worker, packed a couple of firsts — the trademark round hole for swift, one-handed deployment and a right-side pocket clip.

However, more than four decades later, one of the knives in the brand’s recent New Product Reveal 19 is unlike any they have ever made before.
Designed by Eric Glesser, son of Spyderco founder Sal Glesser, the appropriately named ButtonUp boasts a mechanism the brand has (surprisingly) never used before.
Lock talk
So, what’s different here? The brand calls the ButtonUp “Spyderco’s first-ever manual-opening button-lock folder.”
That immediately raised some eyebrows around the GP offices, as early this year, our own Sean Tirman wrote about the Sage 6 Button Lock.
