i have 3 Kizers: 401B, 3404A3, 4404B. the only thing they lack is ball bearings. and this is only a conceptual flaw for me, not functional. they open as smoothly and any ball bearing knife i own from quartermasters to Microtech DOC to CRKT's IKBS knives (e.g., Eros). otherwise these are perfect knives. handling them is pure pleasure. every little detail is perfectly executed. and Kizer, unlike other Chinese knife makers (e.g., Wild Boar, Kevin John, etc.), does not sell knock offs. can their designed be further improved? sure. i'd ditch colorful titanium, add some more blade styles (definitely tango) and classier handle styles, similar to 401B, may be titanium spines/spacers, textured handles (such as Boker's Manaro), a bit more aggressive jimping, more distinctive pocket clips and thumb studs (the flippers are so good that thumb studs can be even removed altogether). and the last but not least: Kizer, please fix your website.
