This is probably the worst QC I’ve seen from Twosun but it still shapes up to be a great little knife after a bit of love. The edge was uneven and dull at the lower half but easily took a shaving edge after fixing. The action was gritty initially but after disassembly and cleaning it’s perfect. One of the most irritating knives to reassemble I’ve ever done. After those two fixes it’s back up to the quality expected from Twosun and worth the half hour of effort for such a low price.
