Customer Reviews

Nice OTF Knife
Dr. A. on May 11, 2023

Got my knife today (5/9), packing and shipping were outstanding. As far as the knife goes, nice quality and well built. Not quite sure an OTF knife guy yet. Will try this one for a while and see where it leads. First impression is that the knife is well built and has an awesome carry pouch (with nice HK stitching). Would I spend $260 again, probably not.
