I have purchased exact dupes of four knives, Buck 303, Buck 102, SAK Huntsman, and a regular Douk Douk. The first three were ordered from Amazon while my wifi was lagging, and were ordered as mistakes. I kept the extra folders, gifted the fixed blades.
With the Douk Douks, I had lost the first one for a couple months, and finally ordered a replacement. Two days after it arrived, my ma calls to tell me she found it in the backyard. Must have fallen out of my pocket.
