SOG builds its XR lock into folders at opposite ends of the price ladder, and Amazon has both ends marked down today. The Kiku XR brings cryo CTS XHP and linen Micarta, while the Terminus XR covers daily carry in blacked-out D2.
The pair makes an easy comparison because the lock is the shared part, so the money only moves the blade steel and the handle material. One knife is the outdoor piece with the sculpted Micarta grip, and the other is the slim black folder that disappears into a pocket. The XR lock works from either side of the handle, so a left-handed carrier runs the same thumb motion, and closing is a pull on the slider and a swing of the blade.
Kiku XR in natural linen Micarta
SOG lists the Kiku XR at $249.95 on its own store, and Amazon’s $136.80 undercuts that hard, with the listing’s $209.99 list price struck through at 35% off. The blade is a modified tanto in cryo CTS XHP, etched right on the flat next to SOG’s skull mark, and it opens off a thumb hole cut through the spine.
The linen Micarta handle carries deep scallops across both scales. It’s a big handful of a folder. That texture keeps the grip planted when hands are wet or cold, and the pocket clip sits deep on the show side. The whole knife is an outdoor tool first and a daily carry second.
In hand, the scallops land where fingers actually wrap, and the XR slider falls under the thumb without shifting the grip.
Flick the slider or roll the thumb hole and the blade swings out.

Terminus XR, the blackout daily carry
The Terminus XR is the same lock in a slimmer and cheaper build, 2.95 inches of cryo D2 in a black finish, 7.21 inches open and 3.2 ounces on the scale. SOG’s own store lists it at $69.95, so Amazon’s $45.95 against a struck $73.99 list price is a genuine cut rather than a relabeled one.
The blade etch spells the full name out longhand, Studies and Observations Group, above the CRYO D2 marking.
The handle is black G10 over the same XR hardware, with a thumb stud for opening and a low-carry clip that reverses for left-side pockets. Nothing about it asks for attention. It’s the knife that stays clipped in work pants Monday through Friday and handles boxes, straps and cord without a second thought.

Buy the Kiku XR at $136.80 if the steel and the Micarta are what you’re paying for and the folder budget stretches past a hundred dollars. Buy the Terminus XR at $45.95 if the knife lives in a work pocket and gets used hard every day.
Skip both if a crossbar-lock folder already rides in your pocket, since the lock is the shared hardware here and a second one buys better materials, not a new mechanism or a new carry.
