I have a few straight razors-that I have no real idea of what to do with, but recently I ended up with a C. Klauberg & Bros. Hone. First, like straight razors, I don't know anything about hones either. After a week or so of trying to research this hone, all I could find is: VINTAGE STRAIGHT RAZOR HONE - YOKOMA RAZOR HONE W/ ORIGINAL WOOD BOX & INST | #1695628397 There isn't even one being sold on the 'bay, nor has there been in ages. So, any help, direct or indirect, would be greatly appreciated. This is my straight inventory: The Tonsonial Gem is above the C. Klauberg & Bros. Yokoma Razor Hone. I think while it might not be shave ready, it's close. But in the end, don't know. An old Boker & Co. with great looking scales and even the blade attachment looks cool, below the hone. Boker & Co. World Columbia Exposition, Chicago 1893 to the left of the hone. It needs a little attention. Sarginson Bros, might also be close to being shave ready, on the far left. A Wadsworth XLNT on the far right that is pretty dull. I doubt I'll go down this rabbit trail, but would like to better understand what it is that I do have.Any help would be greatly appreciated.
