"I wanted to thank you for developing an amazing class.  It was one of the best classes I had attended in a long time. It was incredibly refreshing to me to experience your class… A class that was full of reality-based training and knowledge that I can actually use. You are a true leader with a great warrior mind-set, and someone who obviously does care about the people you train.  You are down-to-earth, obviously well-versed on the topic, and you have a strong background in law enforcement."  Vance from WY, 2013 

"I had no previous knife training. I was looking for entry level information. The class met my expectations and more. Jeff Black is an incredible instructor. The content was appropriate for my ability (it sure opened my eyes to the topic). The delivery was excellent. Jeff easily transitions between prepared remarks and student questions. I had no idea of how well the knife fits into a personal protection plan. For all the BluCore students who are taking firearms training, this class is a must. If nothing else, it will open your eyes to other options" Matthew from CO, 2013

"From start to finish this class was unlike any other instructional course I have ever attended. Jeff Black is truly an exceptional instructor. He brings with him a resume full of real world experience and combines it with a very well though out and constructed curriculum. He does an excellent job of covering a wide range of topics as well as integrating practical drills in a short period of time. I would highly recommend this course. It far exceeded my expectations and I am extremely glad that I had the opportunity to attend." Joseph from CO, 2013
