The old bladesmiths used to come up under a master in the classic  apprentice/mentor relationship. The products they put out reflected not  only the talents and work of the individual, but that of the collective  knowledge being passed down through a long lineage. Lessons and  innovations learned the hard way. Being one of Wayne Goddard's best senior students and close friends,  Jeff's knives carry that kind of old-school weight.
It seems to me that if you were to provide any two knifemakers with  the same quality of raw materials and ask them to produce a certain kind  of blade for a certain kind of job, you'd be leaving them with just two  critical areas in which they could outdo one another: design and  craftmanship. Expertise in these aspects is born only out of experience  and to some far lesser degree, raw talent. 
When I talked to Jeff Crowner about his designs and posed some pointed  questions about his choices in material and geometry I realized pretty  fast that I was talking to someone who not only knew exactly how to make  knives properly, but also someone who knew how to employ them expertly.  Without going into too much detail (Opsec/Persec/Etc) I'll say that if  I'm going to have to throw down with somebody in a dark alley with  blades--Jeff is the absolute last person I'd want to square up with. Period.  So you'll have to take me at my word that in this respect too, Jeff's  combatives knowledge follows a centuries old tradition. His roots in the  Indonesian and Filipino blade arts go seriously deep and his ability to  wield a blade is profoundly scary. 
All I can really say is that as a bushcraft and survival instructor, tracker and  private security professional, knives are  an essential part of my toolbox. I carry and use blades every day in work and personal capacities. I follow the adages to 'Always  upgrade your weaponry' and 'Buy cheap, buy twice.' I research and  fact-check and test and re-test all of my gear before it sees the  field. If something works I stick with and in the end, I place the highest importance on real-world  reliability and performance. Overall I am convinced that with respect to  modern, custom edged tools and weapons there is  nothing that compares with Jeff Crowner's work.
