I met Herb Dunkel many years ago when he traveled to wood carving shows.
Herb's Yellowstone is actually pink in color and was made for him by Norton Abrasives in MA.
I believe it was about the same grit size as the original Green Chromium Oxide which was so popular at the time.
It is a hard...
All three of the videos show how to ROUND THE TIP on your knife, including the one by Worksharp.
Dragging the knife tip off the edge of the stone will quickly ruin the tip.
With any very narrow stone, one should stop the blade on the stone flats and lift it off not drag it over the edge...
Very common to have a crack from earlier bending side pressure, then finally gives up with more normal usage.
The Spyder hole is a design we all enjoy however, it results in less material to resist bending and is the weakest area in the blade.
I also much prefer the horse butt leather,,, it is hard and will minimize the rounding over of the apex if too much pressure is applied to the blade.
Diamond spray works fantastic and needs very little pressure to maximize the apex formation.
Accepting a Rockwell C scale harness number as a single value with only one indentation is very unusual in engineering machine design. To allow for the non precise nature of test numbers we normally give a hardness range, for example Rc 61-63 when specifying a hardness.
The testing machine...
Received the two I ordered on Friday this morning.
Excellent knives, QC is fantastic with very nice edge bevels consistent on both sides with nice grinding finish. Perfectly centered with great detail on the entire knife.
Slight, 1/8 turn, on the pivot screw and a few drops of Nano-Oil on...
