Rough Rider's "Brian Yellowhorse" Arrowhead Pocket knives

Brian Yellowhorse designed a series of Tough Rider knives for Smoky Mountain Knife Works several years ago. The series consisted of twelve knives; a thirteenth knife was later produced. I was recently gifted the Baby Sunfish by North Star Knife Review. This prompted me to review the entire series, of which, I have just six (seven if you include the 13th knife). The question now: Will I go for the other half of the series? Or will I now go for an original Brian Yellowhorse knife which will easily cost more the entire Rough Rider Series!
