A short history of the Model 163 "The Original Livesay RTAK Machete." . No longer made. A copy of the Livesay RTAK in name only is made by Ontario Knife Company. The original Livesay RTAK is a variation inspired by the model 121, Recon Combat Machete, aka; Rapid Deployment designed and manufacture here in Siloam Springs, Arkansas. The original Livesay RTAK was a collaboration between Jeff Randall, and Newt Livesay with modification made on the handle in the Livesay shop. The original RTAK machete were of limited production with only about 375 knives being made. Production was stopped on the original Livesay RTAK when we found out that Ontario Knife Company had begun making the knife. Livesay RTAK machetes have a more ergonomically designed user friendly custom handle, and the blades were differentially heat treated with edges being in the 59-60 Rockwell range. The way we found out that this knife was being made with the same name (RTAK) was when we started getting production knives not made by us back for warranty or rework due to warped, and wrinkled blades. At this point standard production of this knife was halted because I (Newt Livesay) did not want our superior quality blades to be compromised by the copies that were being dumped on the market.
