In the early 1980s, law enforcement sought out Spyderco, requesting that the brand build a folding knife that was slim, easy to carry, one-hand operable and high-performance. Sal Glesser’s outfit obliged, producing the brand’s Police model — one of its longest-running folders still in production.
However, the brand decided not to keep the knife a law enforcement-only offering, opening it up to the public, much to the joy of knife fanatics and collectors everywhere.
The latest in its lineup, the Spyderco Police 4 Lightweight CPM SPY27, is special for its unique combination of materials and features.

The banner feature of this knife — the part that grants it the “Lightweight” in its name — is its handle. On the standard Police model, the knife features stainless steel scales.
In this version, those scales have been replaced with FRN (fiberglass-reinforced nylon) ones — the same material used for all of Spyderco’s Lightweight models. That brings the weight down significantly from 5.4 ounces to 4.2 — a 1.2-ounce decrease (which, in EDC terms, is quite a bit.) That’s also helped by its skeletonized steel liners.
