8 Best Spyderco Non-Locking Folding Knives: From S110V UKPK to the Dog Tag

A locking blade is useful until the lock itself becomes part of the problem. Some buyers live or travel where locking folders face tighter restrictions, while others simply prefer a non-locking knife without giving up modern Spyderco features like lightweight FRN handles, pocket clips, and finger choils. Spyderco's non-locking lineup covers that territory better than any brand in the business — from the premium UK Penknife to the wildly compact Dog Tag Folder.

These knives hold their blade open through spring tension or slipjoint-style resistance rather than a mechanical lock. One warning before you shop: non-locking doesn't automatically mean legal everywhere. Knife laws can hinge on blade length, opening method, carry method, and jurisdiction, so check your local rules first. With that out of the way, the standout of the group is the UK Penknife C94PDBL, the premium pick — a just-under-3-inch CPM S110V blade in midnight-blue FRN, with a reversible tip-up wire clip. You get the familiar format of a modern lightweight EDC folder, minus the lock.

If you'd rather skip the premium steel surcharge, the UK Penknife Drop Point C94PBK3 runs the same non-locking UKPK concept with a roughly 3-inch CTS BD1N blade and black FRN handle for considerably less. The buying decision between the two is mostly a question of how much you value S110V — and as with any steel, the alloy name doesn't guarantee edge life, since heat treatment, geometry, and use all matter. For smaller hands and smaller jobs, the Squeak scales the concept way down: a 2-inch N690Co blade, reversible deep-pocket wire clip, and index-finger choil at around 1.6 ounces.

Then there's the Dog Tag Folder, Serge Panchenko's wild card — a 1.23-inch CPM S30V blade with a flat chisel grind in a carbon-fiber/G-10 laminate body that weighs about 0.9 ounce. There's no pocket clip at all; it's designed to ride like a dog tag. Compared to the UKPK, it trades cutting reach for pure uniqueness, and compared to the Squeak, it drops clipped carry entirely. That's the shape of Spyderco's non-locking lineup: one familiar premium folder, one value take, one purpose-built compact, and one conversation piece — with the caveat that every one of them demands careful technique, because a choil is a safeguard, not a lock.

The Verdict: For anyone who wants modern Spyderco ergonomics without a lock, the UKPK pair leads the way, the Squeak covers compact clipped carry, and the Dog Tag proves non-locking can still be a statement.
