While I have assorted oil stones and diamond stones as well I have also attained fine edges using 'wet or dry' sandpaper (the kind used by car painters) on either a piece of plate glass or my cast iron saw table top along with a drop or two of 3-in-one oil!
I do a fait bit of wood carving as well as leather work and SHARP is essential.
I even resharpen my 'OLFA' blades as leather really chews up edges.
The older the oilstone is, generally the better I like it. (I probably buy every one I see at yard sales!)
The most important element in a cutting blade is the steel used.
Give me a real old butcher's knife, all rusty that nobody will touch, and it becomes my bestest one of all!
Shucks my best wood gauges are aircraft grade chrome molly tubing welded to a steel shaft with a homemade handle that I turn on my lathe.
I have made many lathe tools using files as well, and they sure heep an edge!
My best hunting knife is from a 12 inch nicklson file with a homemade leather grip. That baby can quarter a 1000 lb moose without a honeing, sure keeps an edge ans as I recall that homemade knife has always been honed on 400 grit wet/dry sandpaper!
Stainless=no-no in my book! (well, table knives=OK)
