Not sure if it were its treatment in transit during the holidays... but my unit is really hard to fold and unfold; too much friction between the handle and the comb, may've been crushed under something for a while perhaps. Will see if a few times using it will correct the problem but it's defo not possible to unfold one-handed, and the creaking sound it makes when using two, is worrying if it this doesn't self-correct.Otherwise, a nice product -- the plastic comb has 0 burrs or flashing to catch hair, and handle is finished likewise. Only nitpick is the brass rivet used at the pivot seems undersized, but only long-term use will reveal if it actually is. Even the silk-screened logo is very nice and a cut above the typical PRC-based nonsense-name stuff sold in the marketplace.As I have rather coarse beard hair, the teeth of the comb are also spaced perfectly for me. Would buy again; four stars (potentially five when used a bit longer, re: friction issue) ⭐️⭐️⭐️⭐️ _---UPDATE 28 FEB 25:Have used the Zeus everyday since it arrived -- no durability issues with the rivet, and the handle has broken in a bit and now slides open and shut w/o problems. Purchased another.Since these are handmade, there's a tiny bit of variation in certain dimensions (new comb is slightly less tapered than the first one, and finger notch a bit smaller; location of rivet is slightly different in both where the 'spine' of the comb protrudes above the handle on 1st one and not at all on the new) but functionally they are identical. Perhaps if this were German or Japanese I'd expect tighter mfg tolerances, but for what it is, how it works and what it costs? It's fine.Happy to support an American small mfr, the K11's a keeper. Five stars ⭐️⭐️⭐️⭐️⭐️
