291533 2004-11-14 02:21:00 Hmm, checking in the garage, I see I have a New Zealand Norton Aluminium Oxide combination stone, a Carborundum brand Silicon Carbide one with no country of origin, and a Norton India combination stone made in Brazil! Terry Porritt (14)
291534 2004-11-14 03:12:00 The following are comments only, not recommendations.

The instructions that came with my sharpening stones says: To prevent glazing and ensure a fast, clean cutting action, the use of a thin clear oil is recommended. (D.F. Neatsfoot Oil is ideal.) if the stone becomes clogged, wash with Kerosene.

My ancient tin of Davis Neatsfoot Oil states: For use as a softening and preserving agent for all classes of leather...it is an excellent lubricant for oilstones...guaranteed manufactured solely from animal tissues and free from mineral and vegetable adulterants... manufactured by Davis Gelatine (NZ) Ltd, Christchurch NZ. (That was way back in the 1960's by the way).

A couple of other thoughts:
My Dad used a leather strop to keep his razors sharp.

What about having a chat with a local butcher or other meatworker.

Cheers.

Oil stones need to be soaked in oil overnight or longer.
In the "olden days", heated tallow was used to soak into the stone.

The use of kerosene to loosen up the surface and float the muck out. Then re-oil with engine oil every so often

291538 2004-11-14 11:09:00 It does not need to be an oil stone and it does not become an oil stone until oil is applied to it .
In my previous profession (chef) we used water and dish washing liquid instead of oil and I've even seen attaway paste used as a lub' on a stone .
The secret to sharping knives is the angle (45 deg) and equal strokes on each side, clean and steel often (same angle) during the process and yes the true test of sharpe knife "can you shave with it" .
We used to use stones purchased from our local hardware store, you know the ones, duel surface, fine on one side course on the other

291539 2004-11-14 11:45:00 OK..
how to sharpen a modern steel knife.
Edging tool... I.E a tool with either tungsten wheels or similar to give a new, even edge to the blade.
then a "steel" to take the burr off.
A "steel" can be of diamond compound, my preferance.
To use a stone of any compound would see you there for a month of sundays .. spitting tacks to boot.

291540 2004-11-15 01:34:00 An oil stone can be used without oil . Water is fine . But if oil is used, that stone must be used with oil ever after .

45° seems a bit savage to me . I use that on a cold chisel (uncluded angle 90° , but that's meant for splitting, driven by a hammer, not "cutting" with in a slicing action . .
