Overview & First Impressions
Three Koala Ultras, one 2.56 inch drop point, and a decision about surface finish. The B and S wear bead-blasted or stonewashed titanium; the M is the mirror version, with a polished blade to match. All are 5.83 inches overall, 2.44 ounces, M390 at 60±2 HRC, crossbar lock, ceramic bearings. Same knife, three personalities.
Materials & Construction
M390 in a small drop point is a good pairing: the steel holds an edge well past what a 2.5 inch blade usually sees, and the drop point gives you a usable belly for slicing that a wharncliffe cannot. Titanium handles keep the weight at 2.44 ounces, which is the number that decides whether a knife actually gets carried.
Design & Details
The M version is the one people photograph. Mirror-polished M390 next to polished titanium is a dress-knife look, and it hides the crossbar machining nicely. The B and S versions are the ones people use - a matte or stonewashed finish does not show fingerprints, pocket lint or the fine scratches that a titanium pocket clip always leaves.
Real-World Use
Two-finger grip, three-finger if you choke up on the choil, and it handles packages, cable ties, thread and lunch without complaint. The crossbar lock makes one-hand closing safe, which matters on a small knife where the blade is close to your fingers. It disappears in a coin pocket and does not print.
Ownership Notes
If this is your only small folder, buy the S or B. If it shares a drawer with other users and comes out for occasions, buy the M. On all three, keep the pivot clean, oil the crossbar spring lightly twice a year, and sharpen at a shallow angle so the thin stock does not turn into a wedge. Three folding knives, one frame, and a finish decision that says more about you than the spec sheet does. If this is your only small folder, buy the S or B and stop worrying about fingerprints. The Koala Ultra range is listed at EdcMall with individual photos so you can see the actual blade finish before ordering. Compare it with the Sloth Ultra if you want a wharncliffe instead of a drop point, since the frames are nearly identical. Neither is a hard-use knife, and both reward a light touch on the stones. Pick the one you will actually carry, and the finish argument solves itself. Buyers who already own several EDC knives will recognize this frame immediately, because Trivisa reuses it across the whole range.
Who Is This For?
City carriers, office workers, and anyone who wants a light knife with real steel rather than a novelty blade. It also works as a second knife for people who already carry something bigger for outdoor days. Not enough blade for field dressing or heavy cardboard volume.
Final Verdict
The M is the looker, the S is the keeper. Buy the finish that matches how often you plan to wipe your knife down, and you will be happy with either - the frame and the steel are the same quality across the run.
