Old Hickory- yes it seems the Heat Treatment varies from those when I was a kid...*sigh*.
Still the deal is, even the new ones do just fine for kitchen chores and even out on the property for garden duty, opening feed sacks and the like.
It does not take much to resharpen and even non-knife folks can maintain one with simple sharpening methods.
Norton Combo IB6/IB8 and strop on cardboard.
Arkansas stones from Washita, then Med/Soft and strop on cardboard or leather.
Wet Dry Sandpaper, and starting at about 220, then 400, 600 and strop is fine.
Some folks lost some Old Hickory's in a move, (not sentimental family pcs thank goodness, instead some they had bought).
They wanted the patina look and all...
I used Wet /Dry sandpaper on paint sticks (buff stick) and on a hard flat surface.
I taped off the blade except for edge, and with the blade flat, thinned down the blade edge starting with 220 and going to 800.
Then I did the Moran edge (Convex) by pulling spine back. This edge was scary sharp!
Cleaned and de-greased, I then used Oxy-Blue to "blue" the blade a nice patina.
Moran again on the edge with 800 and that edge is a nice shiny contrast to the patina and sharp!
Kitchen touch ups are easy, getting out the paint sticks (buff sticks) and pulling spine back to do the Moran (convex) edge - If - abrasive is needed.
600 grit works best on these, enough "teeth" to really slice tomatoes and the like.
Often just stropping is enough.
Strop is a 2" belt , bought new that was missing a buckle for $2.
Belt was cut and two 12" pcs were tossed in the sink to get wet.
Then stretched onto a smooth flat pc of scrap wood, and upholstery tacks hammer in. One is the rough side, the other smooth.
It is taut, and is used with NO dressing.
Grandparents did this with the knives back when, they were a bit surprised Grandparents knew Bill Moran and about the Moran Edge. *grin*
Just how folks used to sharpen back in the day - before gidgets and gadgets, bevels , angles and what-not.
Oh these folks have some nice stones...just for most uses this old system works on everything from kitchen to pocket to hunting knives to whatever.
