The BK16 is popular around these parts. Too small for my hand, but seem to fit most. The BK10, and BK12 are also nice blades. Haven't had the BK12, but one of these days I'm sure I will. My wife has her own blades as well. She has her own BK4. She really likes it. She also likes to get in the woods and use her machete I got her last year for Christmas. She loves her BK15, and her BK14 as well. She also likes using her T.M.Hunt Hornet , Breeden necker, Condor Bushcrafter, Mora Companion, and her Zancudo, haha. I think that about covers it. I was thinking about getting her a Leatherman Juice too.
