Overview & First Impressions
The Sloth Ultra is Trivisa's compact wharncliffe, and it comes in three handle builds: PC with copper carbon fiber, GC with plain carbon fiber, and PL with a copper-and-carbon-fiber mix. All three share the same 2.54 inch M390 blade, ceramic bearing pivot, crossbar lock and 5.74 inch overall length. Weight starts at 2.04 ounces.
Materials & Construction
M390 at 60±2 HRC is the reason to buy this instead of a budget wharncliffe. It is a high-vanadium powder steel: it holds a working edge for a long time, resists staining, and punishes lazy sharpening. The wharncliffe profile puts a straight edge low in the hand, which is ideal for draw cuts and box work rather than food prep.
Design & Details
The crossbar lock is the ergonomic story here. It is ambidextrous, it keeps your fingers out of the blade path on closing, and it makes a satisfying click that collectors pretend not to care about. The copper carbon fiber version is the looker of the three - the copper weave catches light and warms up as the handle sits in your hand.
Real-World Use
At two ounces you forget it is in a pocket until you need it. The short wharncliffe blade is superb for opening packaging, cutting zip ties and trimming tape, and it is poor for spreading or slicing anything soft. Bearing pivot means it flicks open easily, which is fun and also means you should keep grit out of the pivot.
Ownership Notes
Choose by how you treat gear. Plain carbon fiber (GC) hides wear best and is the sensible daily pick. Copper carbon fiber (PC) looks best new and shows handling marks. PL sits in between and photographs well. On all three, sharpen the M390 at a shallow angle with diamond stones and strop often rather than grinding. All three are folding knives with the same lock and the same blade, so the finish is the only meaningful choice. If you already own several EDC knives, this is the one that fills the small-and-light gap in the rotation. Every Sloth variant is listed at EdcMall with real photographs, and the copper weave differs noticeably between units. Expect to pay less than a comparable American-made folder, which is the whole reason Trivisa has a following at all. The trade is that warranty work happens overseas, so buy from a seller who answers questions quickly. None of that matters much on a two-ounce knife you will mostly use to open boxes and cut tape.
Who Is This For?
Buyers who want a small, light, genuinely good steel folder for office or city carry. It suits anyone replacing a heavy tactical folder with something they will actually pocket. Skip it if you need blade length for outdoor work; 2.54 inches is a lot less than it sounds.
Final Verdict
Same knife, three costumes. Pick GC for daily use and PC if you want it to look like jewelry. The steel and the lock are the real purchase either way.
