[Duncans ProForge] The Stiff-Upper-Slip Apex Folder (SUS AF)

Description:

The SUS AF- alright... we had fun with this one.

A pocket-sized embodiment of British grit, where understatement meets over-engineering. This slipjoint is built like a London bus: unapologetically solid, quietly brilliant, and always on time.

The black-and-grey carbon fibre scales aren’t just for show; they’re lightweight, grippy even in drizzle, and patterned like a stealthy herringbone suit. Held together by two stainless Torx screws (because Phillips is for amateurs), they lock into integral stainless bolsters and liners. That means the bolsters are the liners—no weak joints, no wobble, just a single forged backbone running the length of the handle. Overbuilt? Maybe. Apologetic? Never.

The D2 clip-point blade rides on a buttery action, snapping to a confident half-stop at 90°—a polite “Mind the gap” before full deployment. Open it with the traditional nail nick (fingernail or coin, your call), and it stiffly snaps into place with just enough thwack to remind you it’s alive, but never enough to scare the vicar.

Closed, it’s a discreet 3.9" of pocket-friendly restraint. Open, it’s a 7" declaration of quiet competence. The blade’s satin finish hides the scars of daily duty—opening boxes, trimming twine, or heroically rescuing a stuck scone from cling film.

The Stiff-Upper Slip: It won’t start a fight. It will finish your to-do list.

And it’ll do it without spilling a drop of tea.

The Stiff-Upper Slip Apex Folder is so SUS AF, it got stopped at airport security for “looking too competent” — then released with an apology and a cuppa.
