Overview
This large Model 4 features a brushed finish blade, fine bead blast titanium bolsters, and textured Kydex scales. Stainless steel clip. Notched thumb ramp. Smooth action. Solid lockup. Excellent work. Mint condition.There are 2 small pin holes on the blade near the bolster. There is a great story to go with these two small marks. The owner of this knife contacted Mr. Carson about these 2 holes and the answer he provided is below.
"As soon as you mentioned the two pinholes, I knew which knife it was. Long story... I carried that folder for a little while. Back in 1993, Buck Knives asked me to join in a project with them. It was the Crosslock.They flew me to El Cajon, and I had that Model 4 in my pocket.
On a tour of their plant, I was introduced to Paul Bos, the world famous heat treater. He asked what knife I had in my pocket and if the heat treating was done by me. I told him it was a Model 4 and yes, I had done the heat treat. He asked me if he could Rockwell test it. The two indentations are from the diamond penetrator tip on his hardness tester. He did a second one to confirm the first.
Paul asked what the hardness was and I told him it was RC59. He smiled and told me that it was dead on 59. That started a great friendship with Paul. I've never used him for his services and do all my own heat treating. It was great for my ego. :)" Blade Steel: ATS-34
