Snappy little auto
Ben W. on Jul 23, 2019

I have the version with a black coated blade. This was my first Protech and as a beginner knife collector, buying this knife was a big milestone in my collecting career. The American flag ano job is superb and well executed. 10/10 would buy again/recommend.
