Hello and welcome to the Sunday Picture Show. Share your Buck knives with others by posting pictures of them here. New or old, plain or custom, user or safe queen, one or a collection, we love to see them all. This weekly tradition was started in 2010 by ItsTooEarly (Armand Hernandez) and Oregon (Steve Dunn). Help keep the tradition alive. Feel free to click that 'LIKE' but lets not let it replace discussing and complimenting each others knives. Enjoy the show. DeSotoSky (Roger Yost)

On this day July 2, 1881 The Assassination of President Garfield.
The 20th President and just months into his Presidency he was shot by Charles Guiteau at the railroad station in Washington D.C. Garfield lived for another 79 days dying on September 19 from sepsis. Guiteau was a real nut job and had an insane notion of importance in his own mind had been annoyingly pressing for a diplomatic posting. He borrowed $15 and purchased a revolver. The revolver was donated to the Smithsonian but has gone missing to history. Guiteau constantly insulted his defense team. He was ultimately hung. His brain is on display at the Museum of the College of Physicians in Philadelphia. If you have nothing better to do, read the Wiki article on Guiteau to see what a nut job he really was. I was curious about Presidential security. After the Civil War about 1/3 of currency in circulation was counterfeit and the Secret Service was formed in 1865 to combat that. The Secret Service started providing Presidential protection after the assassination of McKinley in 1901.

A 105 Pathfinder with micarta spacers this week circa 1969-1972. The time frame for this knife is bracketed by the change from bone hard fiber to micarta spacers in 1969 and the addition of the model number in 1972. A nice specimen with box I'm pleased to have in my collection

Hello Everyone,
I have a couple of 110 Buckcotes with Dymondwood Handles. These gold blade knives are sharpened on one side only. Does anyone know the angle these were sharpened at?
I like that they matched the same color of Wood for the handles. One is from 1987 and the other is from 1988. These knives blades have a Titanium Nitride coating and on a hardness scale maxed it out at 80. Found that these knives cut better than ones sharpened on both sides.

Buck 105 Pathfinder one-line (top & center) that my cousin bought from the MCX at Camp Lejeune NC on 28 June 1966. Bottom picture is my Buck 105 Pathfinder (four-spacer, three-line) that I bought from the Post Exchange at Aberdeen Proving Ground MD in the fall of 1976 (my box and packaging long, long gone).

Good morning everybody. Roger, thank you for the history. You stated some facts I never knew. Also thanks to everyone else for sharing.
I wasn't able to produce a group photo of my small Buck knife collection. (If you could call it that) :)
Here is one that was a surprise to me. After gifting my 110 Slim Select to the farmer we bought some firewood from, my wife shocked me with this knife for Fathers Day. I had told her if I ever do replace it, I'd want one in O.D.

If I may add, thanks to pat9198 pat9198 for gifting me a 112 Slim Select!

Your knives have blades coated with ZrN (Zirconium Nitride). It is harder than TiN (Titanium Nitride) 85HRC vs 82HRC. If you look at the photo, you can see a variation in the width of the sharpened bevels. A wider bevel indicates a more acute edge. If I put the TiN (dark Gold) coated blade on the Goniometer, it measures about 10 degrees. A double bevel Buck shoots for 30 degrees included. The left knife in the picture is 10 degrees included. It is inherently 3X as sharp as a regular Buck blade. Razors utilize skinny edges also.
In use the blade wears away faster than the coating on the micro edge, so the the knife is self sharpening.View attachment 2238527

Here is the article I got my info from.

It’s a little difficult to measure hardness on the Rockwell C scale on coatings as thin as the IonFusion (BuckCote) layers. They might infer HRC ratings by what scratches what. A 100 HRC rating on the C scale means that the inverted Diamond pyramid did not penetrate the test block. I have read elsewhere that the PVD (Physical Vapor Deposition) coatings used by Buck have the following values: TiN=(82 HRC), ZrN=(85 HRC), TiCN=(88 HRC), and TiAlN=(92 HRC).
