If you're hankering for a small auto knife for EDC purposes, the SigTac Auto knife might suit you. At just 2.6 oz this auto features a 3.1" ATS-34 Nitron finished blade. Upsides on the SigTac Auto are the lightweight, stylish looks, good clip (mount it deeper), wisely thin scales, good steel, excellent jimping on the thumb ramp, and good grind on the blade. But it has some downsides too: short blade pretty much suited for EDC tasks only, SLOW auto deployemnt, and a loose lockup. Like I've said times before, a well-designed and balance manual action knife is just as fast (and sometimes faster and simpler) and I generally prefer one over an auto. But the SigTac Auto remains a decent option for a small and lighweight auto knife that won't break the bank.
