It's not a collecting focus but I have collected a few knives over the years. Mostly military stuff. Don't have a lot of photos of knives though.
World War II era second pattern (bottom) and third pattern (top) Fairbairn Sykes knives. Shown with a Webley Mark IV. I love both U.S. and British militaria.
I like racing, I like knives. What's the best combo? Duh.
Below is a Roland Riddle Custom Knife Set - Made for Racing Legend Ralph Johnson (Smokey Yunick's right hand man)
Made by Master Bladesmith Roland Riddle in Andes, NY. Absolutely amazing work, including scrimshaw by his personal friend, Denise Kondrla. Sadly, Riddle died in July 2001 at age 52 so his craft does not go on but this set is from his most masterful years.
Ralph Johnson's Initials(RRJJ - Ralph R Johnson Junior) are inscribed on one side, an image of a wolf on the other side, all done by hand. The scrimshaw is signed and dated on each, one blade 1997, the other 1998. Beautiful African Ivory handles.
