Thanks for the heads up Seal Billy. I just ordered a BK4 aka Machax before they're gone. I missed out on the entire BK&T line back when they were built by Camillus. I was glad at the second chance offered by Ka-bar, and have collected every BK model except the Machax...............until a couple minutes ago.
Based on the drop in prices/availability, I've got a hunch the BK5 is being cut also (sorry for the pun).
If you plan on using it you will love it.
Mine came today and I must admit it's cooler than I expected. I already knew and understood the shape and handle angle, but it's shorter and lighter than I expected. Most of the weight is up front where it needs to be, and like all full size BK's, it's got a very comfortable handle. This thing just might out chop other blades in it's weight class...........or with less effort. Accurately hitting the sweet spot will take some practice, but right now it appears more efficient than the heavier BK9 with its weight distributed full-length.
While it's one of the most unconventional knives I now own, it might come close to being that perfect do-all large knife to pair up with a small mora or folder.
Thanks for starting this thread.
